The putative bioactive surface of insect-selective scorpion excitatory neurotoxins. (1/601)

Scorpion neurotoxins of the excitatory group show total specificity for insects and serve as invaluable probes for insect sodium channels. However, despite their significance and potential for application in insect-pest control, the structural basis for their bioactivity is still unknown. We isolated, characterized, and expressed an atypically long excitatory toxin, Bj-xtrIT, whose bioactive features resembled those of classical excitatory toxins, despite only 49% sequence identity. With the objective of clarifying the toxic site of this unique pharmacological group, Bj-xtrIT was employed in a genetic approach using point mutagenesis and biological and structural assays of the mutant products. A primary target for modification was the structurally unique C-terminal region. Sequential deletions of C-terminal residues suggested an inevitable significance of Ile73 and Ile74 for toxicity. Based on the bioactive role of the C-terminal region and a comparison of Bj-xtrIT with a Bj-xtrIT-based model of a classical excitatory toxin, AaHIT, a conserved surface comprising the C terminus is suggested to form the site of recognition with the sodium channel receptor.  (+info)

Purification from black widow spider venom of a protein factor causing the depletion of synaptic vesicles at neuromuscular junctions. (2/601)

The aqueous extract of the venom glands of black widow spiders was fractionated on a column of Sephadex G-200 and then on a column of DEAE-Sephadex A-50 pH 8.2. A protein fraction was obtained that caused a great increase in the frequency of occurrence of miniature end plate potentials at the frog neuromuscular junction, and caused swelling of the nerve terminals and depleted them of their vesicles. The fraction consists of a least four protein components that are similar in their molecular weights (about 130,000) and isoelectric points (ranging from pH 5.2 to 5.5) and are immunologically indistinguishable. It contains no sugar residues and has little or no lipolytic or proteolytic activity. The fraction is toxic to mice and is different from the fractions that act on houseflies, the crayfish stretch receptor and the cockroach heart. It seems pure enough to warrant a detailed study of its site and mode of action.  (+info)

Contribution of potassium conductances to a time-dependent transition in electrical properties of a cockroach motoneuron soma. (3/601)

Contribution of potassium conductances to a time-dependent transition in electrical properties of a cockroach motoneuron soma. The cell body of the cockroach (Periplaneta americana) fast coxal depressor motoneuron (Df) displays a time-dependent change in excitability. Immediately after dissection, depolarization evokes plateau potentials, but after several hours all-or-none action potentials are evoked. Because K channel blockers have been shown to produce a similar transition in electrical properties, we have used current-clamp, voltage-clamp and action-potential-clamp recording to elucidate the contribution of different classes of K channel to the transition in electrical activity of the neuron. Apamin had no detectable effect on the neuron, but charybdotoxin (ChTX) caused a rapid transition from plateau potentials to spikes in the somatic response of Df to depolarization. In neurons that already produced spikes when depolarized, ChTX increased spike amplitude but did not increase their duration nor decrease the amplitude of their afterhyperpolarization. 4-Aminopyridine (4-AP) (which selectively blocks transient K currents) did not cause a transition from plateau potentials to spikes but did enhance oscillations superimposed on plateau potentials. When applied to neurons that already generated spikes when depolarized, 4-AP could augment spike amplitude, decrease the latency to the first spike, and prolong the afterhyperpolarization. Evidence suggests that the time-dependent transition in electrical properties of this motoneuron soma may result, at least in part, from a fall in calcium-dependent potassium current (IK,Ca), consequent on a gradual reduction in [Ca2+ ]i. Voltage-clamp experiments demonstrated directly that outward K currents in this neuron do fall with a time course that could be significant in the transition of electrical properties. Voltage-clamp experiments also confirmed the ineffectiveness of apamin and showed that ChTX blocked most of IK,Ca. Application of Cd2+ (0.5 mM), however, caused a small additional suppression in outward current. Calcium-insensitive outward currents could be divided into transient (4-AP-sensitive) and sustained components. The action-potential-clamp technique revealed that the ChTX-sensitive current underwent sufficient activation during the depolarizing phase of plateau potentials to enable it to shunt inward conductances. Although the ChTX-sensitive conductance apparently makes little contribution to spike repolarization, the ChTX-resistant IK,Ca does make a significant contribution to this phase of the action potential. The 4-AP-sensitive current began to develop during the rising phase of both action potentials and plateau potentials but had little effect on the electrical activity of the neuron, probably because of its relatively small amplitude.  (+info)

cDNA cloning of an adult male putative lipocalin specific to tergal gland aphrodisiac secretion in an insect (Leucophaea maderae). (4/601)

Lma-P22 is a cuticular surface protein specific to the tergal gland secretion of Leucophaea maderae adult males which is ingested by females just before copulation. The complete Lma-P22 cDNA sequence was determined by RT-PCR using primers based on Edman degradation fragments. The recombinant protein expressed in Escherichia coli was recognized by an anti-Lma-P22 antibody. Northern blot analysis indicates that the corresponding mRNA is transcribed only in the epidermis of male tergites. Sequence analysis indicated that Lma-P22 deduced protein belongs to the lipocalin family. Lipocalins are extracellular proteins which carry hydrophobic compounds and some of them can bind sexual pheromone in vertebrates. Lma-P22 is the first example of a lipocalin-like protein involved in insect sexual behavior.  (+info)

Clinical experience and results of a Sentinel Health Investigation related to indoor fungal exposure. (5/601)

This is a review of exposure conditions, clinical presentation, and morbidity of children and adults with indoor fungal exposure such as toxic Stachybotrys chartarum. Indoor exposure was characterized using different methods including microscopic, culture, cytotoxicity screening tests, and chemical analyses. Clinical case histories and physical and laboratory findings are presented of children (age < 18 years, n = 22; mean age 9 years; 60% females) and adults (age >18 years, n = 125; mean age 39 years, 67% females) who consulted an environmental health specialty clinic. In the pediatric patients' exposure history, widespread fungal contamination of water-damaged building materials with known toxic or allergic fungi was identified. Primarily disorders of the respiratory system, skin, mucous membranes, and central nervous system were reported. Some enumeration and functional laboratory abnormalities, mainly of the lymphatic blood cells, were observed, although no statistically significant differences were found. IgE or IgG fungi-specific antibodies, used as exposure markers, were positive in less than 25% of all tested cases. In an evaluation of a symptomatic girl 11 years of age (sentinel case investigation) living in an apartment with verified toxigenic fungi (i.e., S. chartarum), several health indicators showed improvement after exposure cessation.  (+info)

A K+ channel-blocking peptide from venom of Chinese scorpion Buthus martensii Karsch. (6/601)

AIM: To purify and characterize a potassium channel blocker (BmP-3) from the venom of Chinese scorpion Buthus martensii Karsch. METHODS: 1. Purification was carried out by gel-filtration, cation-exchange, and reversed-phase chromatographies. N-terminal was directly sequenced by double-coupling manual method. Molecular weight was determined on an electrospray ionization mass spectrometer. Amino acid composition was analyzed after acidic hydrolysis for 20 h in HCl 6 mol.L-1 at 110 degrees C. 2. Toxicity tests were conducted in mice and cockroaches. 3. The inhibitory effects of BmP-3 on K+ channels were tested in acutely dissociated rat hippocampal pyramidal neurons using whole-cell patch-clamp configuration. RESULTS: 1. A pure peptide (BmP-3, 8.1 mg) was obtained, about 0.08% of total proteins of the venom. The N-terminal sequences were VGCEE and the molecular weight was 2938 in ESI-mass spectra. 2. No death occurred at the dosage of 200 micrograms in mice and 8 micrograms in cockroaches. 3. The peptide at 10 mumol.L-1 reduced the peak outward K+ currents by 63% +/- 4% in vitro. CONCLUSION: BmP-3 inhibited K+ channels.  (+info)

Role of allergy in nasal polyps of Thai patients. (7/601)

As distinct from many countries, allergy in Thailand is of the perennial type which may play a role in the formation of nasal polyps. Forty consecutive patients with nasal polyps and 30 normal subjects as control were studied at the Allergy Clinic, Department of Otolaryngology, Pramongkutklao Hospital. A positive clinical history and skin allergy testing are diagnostic criteria for allergy. In the nasal polyps group, these were 28 males and 12 females, aged between 12-65 years, with an average age of 38.5 years. In the control group, there were 18 males and 12 females, aged between 15-53 yeas, with an average age of 34 years. All had received prick skin testing with 6 common aeroallergens. The prick skin test was considered positive when the wheal was > or = 3 mm with surrounding erythema. Twenty-four of 40 patients (60%) with nasal polyps had a positive prick skin test, while 6 in the 30 control cases (20%) had a positive prick skin test. This difference was statistically significant (P = 0.0019), Odd's ratio = 6.0 which means allergic persons were 6 times more prone to have polyps form than normal persons.  (+info)

Post-translational modifications of the insect sulfakinins: sulfation, pyroglutamate-formation and O-methylation of glutamic acid. (8/601)

We identified and chemically characterized the two major forms of sulfakinins from an extract of 800 corpora cardiaca/corpora allata complexes of the American cockroach, Periplaneta americana. Bioactivity during the purification was monitored by measuring heart beat frequency in a preparation in situ. By Edman degradation analysis and MS, these main forms were identified as having the primary structures Pea-SK [EQFDDY(SO(3)H)GHMRFamide] and Lem-SK-2 [pQSDDY(SO(3)H)GHMRFamide]. The sulfation was confirmed by UV, MS and peptide synthesis. In addition, post-translationally modified sulfakinins of both major forms were isolated and identified. Firstly, nonsulfated forms of these peptides are present in considerable amounts in the corpora cardiaca/allata. Secondly, the N-terminally blocked Pea-SK and the nonblocked Lem-SK-2 occur naturally in neurohaemal release sites. Thirdly, modified Pea-SK with O-methylated glutamic acid occurs which is not an artefact of peptide purification. The major forms of the sulfakinins were shown to be highly active on both the heart and hindgut with threshold concentrations of approximately 5 x 10(-10) M (heart) and 2 x 10(-9) M (hindgut).  (+info)

Cockroaches are not a medical condition or disease. They are a type of insect that can be found in many parts of the world. Some species of cockroaches are known to carry diseases and allergens, which can cause health problems for some people. Cockroach allergens can trigger asthma symptoms, especially in children. Additionally, cockroaches can contaminate food and surfaces with bacteria and other germs, which can lead to illnesses such as salmonellosis and gastroenteritis.

If you have a problem with cockroaches in your home or workplace, it is important to take steps to eliminate them to reduce the risk of health problems. This may include cleaning up food and water sources, sealing entry points, and using pesticides or hiring a professional pest control service.

"Periplaneta" is a genus name that refers to a group of large, winged insects commonly known as cockroaches. The two most common species in this genus are the American cockroach (Periplaneta americana) and the German cockroach (Periplaneta germantica). These insects are typically found in warm, humid environments and can often be seen scurrying across floors or walls in homes, restaurants, and other buildings. They are known to carry diseases and can cause allergies and asthma attacks in some people.

Blattellidae is a family of small to medium-sized insects commonly known as cockroaches or wood cockroaches. They are closely related to the larger Blaberidae family, which includes many of the tropical cockroaches. Blattellidae species are found worldwide and include some of the most common and widespread cockroaches, such as the German cockroach (Blattella germanica) and the brown-banded cockroach (Supella longipalpa).

These insects are generally small, with adults ranging in size from about 1/2 to 3/4 inch (1.2 to 1.9 centimeters) in length. They have a flattened body and long, slender antennae. The wings of Blattellidae species are well-developed, but they are not strong flyers. Instead, they tend to scuttle quickly away when disturbed.

Blattellidae cockroaches are omnivorous, feeding on a wide variety of plant and animal materials. They can be found in a range of habitats, including forests, grasslands, and urban environments. Some species are adapted to living in close association with humans and can be found in homes, restaurants, and other buildings.

Like all cockroaches, Blattellidae species have the potential to carry and transmit diseases, as well as cause allergic reactions in some people. It is important to take steps to prevent and control infestations of these pests in order to maintain a healthy living environment.

An allergen is a substance that can cause an allergic reaction in some people. These substances are typically harmless to most people, but for those with allergies, the immune system mistakenly identifies them as threats and overreacts, leading to the release of histamines and other chemicals that cause symptoms such as itching, sneezing, runny nose, rashes, hives, and difficulty breathing. Common allergens include pollen, dust mites, mold spores, pet dander, insect venom, and certain foods or medications. When a person comes into contact with an allergen, they may experience symptoms that range from mild to severe, depending on the individual's sensitivity to the substance and the amount of exposure.

I'm sorry for any confusion, but "pest control" is not a term typically used in medical definitions. Pest control refers to the regulation or management of species considered to be pests, which can include insects, rodents, and other organisms that can cause damage to crops, transmit diseases, or otherwise negatively impact human activities.

In a medical context, you might be looking for information on "pesticide exposure" or "insect-borne diseases." Pesticide exposure refers to the contact with pesticides, which are substances used to control pests. These exposures can occur through inhalation, ingestion, or skin contact and may lead to a variety of health effects depending on the type and amount of pesticide involved. Insect-borne diseases are illnesses transmitted to humans through the bite of infected insects, such as mosquitoes, ticks, or fleas. Examples include malaria, Lyme disease, and Zika virus infection.

Hemolymph is not a term typically used in human medicine, but it is commonly used in the study of invertebrates, particularly arthropods such as insects and crustaceans. Hemolymph is the fluid that circulates within the open circulatory system of these animals, serving multiple functions similar to both blood and lymphatic systems in vertebrates.

In simpler terms, hemolymph is a combined fluid that performs the functions of both blood and lymph in invertebrates. It serves as a transport medium for nutrients, waste products, hormones, and immune cells (hemocytes) throughout the body. Hemolymph does not contain red and white blood cells like human blood; instead, hemocytes are the primary cellular components responsible for immune responses and wound healing in these animals.

Hypersensitivity is an exaggerated or inappropriate immune response to a substance that is generally harmless to most people. It's also known as an allergic reaction. This abnormal response can be caused by various types of immunological mechanisms, including antibody-mediated reactions (types I, II, and III) and cell-mediated reactions (type IV). The severity of the hypersensitivity reaction can range from mild discomfort to life-threatening conditions. Common examples of hypersensitivity reactions include allergic rhinitis, asthma, atopic dermatitis, food allergies, and anaphylaxis.

An antigen is any substance that can stimulate an immune response, leading to the production of antibodies or activation of immune cells. In plants, antigens are typically found on the surface of plant cells and may be derived from various sources such as:

1. Pathogens: Plant pathogens like bacteria, viruses, fungi, and oomycetes have unique molecules on their surfaces that can serve as antigens for the plant's immune system. These antigens are recognized by plant pattern recognition receptors (PRRs) and trigger an immune response.
2. Endogenous proteins: Some plant proteins, when expressed in abnormal locations or quantities, can be recognized as foreign by the plant's immune system and elicit an immune response. These proteins may serve as antigens and are involved in self/non-self recognition.
3. Glycoproteins: Plant cell surface glycoproteins, which contain carbohydrate moieties, can also act as antigens. They play a role in plant-microbe interactions and may be recognized by both the plant's immune system and pathogens.
4. Allergens: Certain plant proteins can cause allergic reactions in humans and animals when ingested or inhaled. These proteins, known as allergens, can also serve as antigens for the human immune system, leading to the production of IgE antibodies and triggering an allergic response.
5. Transgenic proteins: In genetically modified plants, new proteins introduced through genetic engineering may be recognized as foreign by the plant's immune system or even by the human immune system in some cases. These transgenic proteins can serve as antigens and have been a subject of concern in relation to food safety and potential allergies.

Understanding plant antigens is crucial for developing effective strategies for plant disease management, vaccine development, and improving food safety and allergy prevention.

I'm sorry for any confusion, but "Insect Proteins" is not a recognized medical term. However, I can provide some information about insect protein from a nutritional and food science perspective.

Insect proteins refer to the proteins that are obtained from insects. Insects are a rich source of protein, and their protein content varies by species. For example, mealworms and crickets have been found to contain approximately 47-63% and 60-72% protein by dry weight, respectively.

In recent years, insect proteins have gained attention as a potential sustainable source of nutrition due to their high protein content, low environmental impact, and the ability to convert feed into protein more efficiently compared to traditional livestock. Insect proteins can be used in various applications such as food and feed additives, nutritional supplements, and even cosmetics.

However, it's important to note that the use of insect proteins in human food is not widely accepted in many Western countries due to cultural and regulatory barriers. Nonetheless, research and development efforts continue to explore the potential benefits and applications of insect proteins in the global food system.

'Clusia' is a genus of flowering plants in the family Clusiaceae, also known as Guttiferae. These plants are native to the Americas, and they include trees, shrubs, and vines. Some species of Clusia are grown for ornamental purposes due to their attractive flowers and glossy leaves. However, some species can be invasive in certain areas and cause problems for local ecosystems.

It's worth noting that 'Clusia' is not a medical term, so it doesn't have a specific medical definition. If you have any questions about a particular plant or its medicinal properties, I would recommend consulting with a healthcare provider or a botanical expert.

I apologize for any confusion, but "Pyroglyphidae" is not a medical term. It is actually a family of small arthropods, specifically mites, that are often found in houses and other buildings. These mites are commonly known as dust mites or storage mites, and some species are associated with allergies and asthma symptoms in humans. If you have any questions related to medical terminology, I'll be happy to help!

Immunoglobulin E (IgE) is a type of antibody that plays a key role in the immune response to parasitic infections and allergies. It is produced by B cells in response to stimulation by antigens, such as pollen, pet dander, or certain foods. Once produced, IgE binds to receptors on the surface of mast cells and basophils, which are immune cells found in tissues and blood respectively. When an individual with IgE antibodies encounters the allergen again, the cross-linking of IgE molecules bound to the FcεRI receptor triggers the release of mediators such as histamine, leukotrienes, prostaglandins, and various cytokines from these cells. These mediators cause the symptoms of an allergic reaction, such as itching, swelling, and redness. IgE also plays a role in protecting against certain parasitic infections by activating eosinophils, which can kill the parasites.

In summary, Immunoglobulin E (IgE) is a type of antibody that plays a crucial role in the immune response to allergens and parasitic infections, it binds to receptors on the surface of mast cells and basophils, when an individual with IgE antibodies encounters the allergen again, it triggers the release of mediators from these cells causing the symptoms of an allergic reaction.

Chlorphenamidine is a first-generation antihistamine drug that is primarily used to treat allergic reactions. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Chlorphenamidine may also have some anticholinergic and sedative effects.

It's important to note that Chlorphenamidine is not commonly used in modern clinical practice due to its adverse effects such as neurotoxicity, which can cause symptoms like dizziness, unsteady gait, and in severe cases, coma. Therefore, it has been largely replaced by safer and more effective antihistamine drugs.

If you have any questions or concerns about medications, including Chlorphenamidine, it's always best to consult with a healthcare professional.

'Insect control' is not a term typically used in medical definitions. However, it generally refers to the methods and practices used to manage or reduce the population of insects that can be harmful or disruptive to human health, food supply, or property. This can include various strategies such as chemical pesticides, biological control agents, habitat modification, and other integrated pest management techniques.

In medical terms, 'vector control' is a more relevant concept, which refers to the specific practices used to reduce or prevent the transmission of infectious diseases by insects and other arthropods that act as disease vectors (such as mosquitoes, ticks, and fleas). Vector control measures may include the use of insecticides, larvicides, biological control agents, environmental management, personal protection methods, and other integrated vector management strategies.

In medical terms, "dust" is not defined as a specific medical condition or disease. However, generally speaking, dust refers to small particles of solid matter that can be found in the air and can come from various sources, such as soil, pollen, hair, textiles, paper, or plastic.

Exposure to certain types of dust, such as those containing allergens, chemicals, or harmful pathogens, can cause a range of health problems, including respiratory issues like asthma, allergies, and lung diseases. Prolonged exposure to certain types of dust, such as silica or asbestos, can even lead to serious conditions like silicosis or mesothelioma.

Therefore, it is important for individuals who work in environments with high levels of dust to take appropriate precautions, such as wearing masks and respirators, to minimize their exposure and reduce the risk of health problems.

'Isoptera' is an outdated term for a taxonomic order of social insects commonly known as termites. These eusocial insects are closely related to cockroaches and share some similarities in their appearance, but they have specialized castes including workers, soldiers, and reproductives that live in colonies. Termites feed on wood, plant fibers, and other materials containing cellulose, which they break down with the help of symbiotic protozoa living in their gut. The order Isoptera is no longer recognized by modern taxonomists, who now place termites within the cockroach family Blattodea.

I apologize for any confusion, but "insects" are not a medical term. Insects are small air-breathing arthropods that have a segmented body with six legs and usually have wings. They make up the largest group of animals on Earth, with over a million described species.

If you're looking for information about a specific medical condition or topic, please provide more details so I can offer a relevant response.

Indoor air pollution refers to the contamination of air within buildings and structures due to presence of particles, gases, or biological materials that can harmfully affect the health of occupants. These pollutants can originate from various sources including cooking stoves, heating systems, building materials, furniture, tobacco products, outdoor air, and microbial growth. Some common indoor air pollutants include particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, volatile organic compounds (VOCs), and mold. Prolonged exposure to these pollutants can cause a range of health issues, from respiratory problems to cancer, depending on the type and level of exposure. Effective ventilation, air filtration, and source control are some of the strategies used to reduce indoor air pollution.
