Carbon 13 NMR study of nonenzymatic reactions of pyridoxal 5'-phosphate with selected amino acids and of related reactions. (1/2410)

Carbon 13 nuclear magnetic resonance spectroscopy has been used to monitor the nonenzymatic reactions of pyridoxal 5'-phosphate with glycine, alanine, valine, serine, and with several other model compounds. Isotopically enriched amino acids were employed so that low concentrations could be utilized while still allowing relatively rapid acquisition of spectral data. The results for alanine and serine are particularly noteworthy in that alanine is deaminated to pyruvate and pyruvate is aminated to alanine, but contrary to the enzymatic reactions of various serine dehydratases wherein serine is converted to pyruvate, the nonenzymatic reaction utilizing serine results in hydroxypruvate rather than pyruvate formation. In the reverse reaction, hydroxypyruvate is aminated to serine but very inefficiently relative to the amination of pyruvate to alanine. The experimental results have been formulated into a proposed reaction mechanism for deamination of amino acids by pyridoxal-P. (+info)

Hierarchical cluster analysis applied to workers' exposures in fiberglass insulation manufacturing. (2/2410)

The objectives of this study were to explore the application of cluster analysis to the characterization of multiple exposures in industrial hygiene practice and to compare exposure groupings based on the result from cluster analysis with that based on non-measurement-based approaches commonly used in epidemiology. Cluster analysis was performed for 37 workers simultaneously exposed to three agents (endotoxin, phenolic compounds and formaldehyde) in fiberglass insulation manufacturing. Different clustering algorithms, including complete-linkage (or farthest-neighbor), single-linkage (or nearest-neighbor), group-average and model-based clustering approaches, were used to construct the tree structures from which clusters can be formed. Differences were observed between the exposure clusters constructed by these different clustering algorithms. When contrasting the exposure classification based on tree structures with that based on non-measurement-based information, the results indicate that the exposure clusters identified from the tree structures had little in common with the classification results from either the traditional exposure zone or the work group classification approach. In terms of the defining homogeneous exposure groups or from the standpoint of health risk, some toxicological normalization in the components of the exposure vector appears to be required in order to form meaningful exposure groupings from cluster analysis. Finally, it remains important to see if the lack of correspondence between exposure groups based on epidemiological classification and measurement data is a peculiarity of the data or a more general problem in multivariate exposure analysis.

A new rapid technique for the fixation of thyroid gland surgical specimens. (3/2410)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.

Characterization of socio-psychological stress-induced antinociception in the formalin test in mice. (4/2410)

The antinociceptive effect induced by exposure to socio-psychological (PSY) stress using a communication box was assessed by the formalin test in mice, compared with those by exposure to footshock (FS) stress and forced swimming (SW) stress. After the termination of stress exposure, whereas exposure to FS- and SW-stress resulted in the attenuation of the formalin-induced biphasic pain response over 15 min, no appreciable antinociceptive effect was found in the case of PSY stress. When exposure to PSY stress was started during the period of early or late phase of pain after the formalin injection, the antinociceptive effect was maintained for 5-15 min; however, further exposure to PSY stress was not effective for producing antinociception. In the tail-pinch test, likewise, exposure to PSY stress longer than 5 min rather decreased the intensity of antinociception. We conclude that PSY stress in this tonic pain paradigm produces antinociception, but further continuous exposure to the emotional stress caused mice to become recuperative even in such a fear-inducing situation.

Immunofluorescence detection of ezrin/radixin/moesin (ERM) proteins with their carboxyl-terminal threonine phosphorylated in cultured cells and tissues. (5/2410)

Ezrin/radixin/moesin (ERM) proteins are thought to play an important role in organizing cortical actin-based cytoskeletons through cross-linkage of actin filaments with integral membrane proteins. Recent in vitro biochemical studies have revealed that ERM proteins phosphorylated on their COOH-terminal threonine residue (CPERMs) are active in their cross-linking activity, but this has not yet been evaluated in vivo. To immunofluorescently visualize CPERMs in cultured cells as well as tissues using a mAb specific for CPERMs, we developed a new fixation protocol using trichloroacetic acid (TCA) as a fixative. Immunoblotting analyses in combination with immunofluorescence microscopy showed that TCA effectively inactivated soluble phosphatases, which maintained the phosphorylation level of CPERMs during sample processing for immunofluorescence staining. Immunofluorescence microscopy with TCA-fixed samples revealed that CPERMs were exclusively associated with plasma membranes in a variety of cells and tissues, whereas total ERM proteins were distributed in both the cytoplasm and plasma membranes. Furthermore, the amounts of CPERMs were shown to be regulated in a cell and tissue type-dependent manner. These findings favored the notion that phosphorylation of the COOH-terminal threonine plays a key role in the regulation of the cross-linking activity of ERM proteins in vivo. (+info)

Antinociceptive properties of the new alkaloid, cis-8, 10-di-N-propyllobelidiol hydrochloride dihydrate isolated from Siphocampylus verticillatus: evidence for the mechanism of action. (6/2410)

The antinociceptive action of the alkaloid cis-8, 10-di-n-propyllobelidiol hydrochloride dehydrate (DPHD), isolated from Siphocampylus verticillatus, given i.p., p.o., i.t., or i.c.v., was assessed in chemical and thermal models of nociception in mice, such as acetic acid-induced abdominal constriction, formalin- and capsaicin-induced licking, and hot-plate and tail-flick tests. DPHD given by i.p., p.o., i.t., or i.c.v. elicited significant and dose-related antinociception. At the ID50 level, DPHD was about 2- to 39-fold more potent than aspirin and dipyrone, but it was about 14- to 119-fold less potent than morphine. Its analgesic action was reversed by treatment of animals with p-chlorophenylalanine, naloxone, cyprodime, naltrindole, nor-binaltrorphimine, L-arginine, or pertussis toxin. Its action was also modulated by adrenal-gland hormones but was not affected by gamma-aminobutyric acid type A or type B antagonist, bicuculine, or phaclofen, nor was it affected by glibenclamide. DPHD, given daily for up to 7 days, did not develop tolerance to itself nor did it induce cross-tolerance to morphine. However, animals rendered tolerant to morphine presented cross-tolerance to DPHD. The antinociception of DPHD was not secondary to its anti-inflammatory effect, nor was it associated with nonspecific effects such as muscle relaxation or sedation. DPHD, in contrast to morphine, did not decrease charcoal meal transit in mice, nor did it inhibit electrical field stimulation of the guinea pig ileum or mouse vas deferens in vitro. Thus, DPHD produces dose-dependent and pronounced systemic, spinal, and supraspinal antinociception in mice, including against the neurogenic nociception induced by formalin and capsaicin. Its antinociceptive effect involves multiple mechanisms of action, namely interaction with mu, delta, or kappa opioid systems, L-arginine-nitric oxide and serotonin pathways, activation of Gi protein sensitive to pertussis toxin, and modulation by endogenous glucocorticoids.

Vaccination with experimental feline immunodeficiency virus vaccines, based on autologous infected cells, elicits enhancement of homologous challenge infection. (7/2410)

Cats were vaccinated with fixed autologous feline immunodeficiency virus (FIV)-infected cells in order to present viral proteins to the immune system of individual cats in an MHC-matched fashion. Upon vaccination, a humoral response against Gag was induced. Furthermore, virus-neutralizing antibodies were detected in a Crandell feline kidney cell-based neutralization assay, but not in a neutralization assay based on primary peripheral blood mononuclear cells. Despite the induction of these FIV-specific responses, vaccinated cats were not protected. Instead, accelerated virus replication was found, an observation similar to what previous experiments using other vaccine candidates have shown. Here, the results of the present study are discussed in the light of enhancement of lentivirus infections as a complicating factor in lentivirus vaccine development. (+info)

Halothane effect on formalin-induced paw edema and flinching in rat. (8/2410)

The formalin test is a model of injury-produced inflammatory pain. Anesthetics, in clinically relevant concentrations, affect neutrophils and immune suppression. This study was to determine whether halothane reliably inhibits inflammatory reaction and formalin induced pain behavior or does not. Rats were exposed to 100% oxygen (control) or halothane, respectively for 30 min and then 24 hr later five percent formalin test was assessed. The base values of the paw's diameter were obtained earlier, and then formalin induced edema was assessed by measuring diameters of the injected paws at 5 min, 1 hr, 4 hr and 24 hr after the injection. Nociceptive behavior was quantified by counting the number of times with the paw flinched at 5 min intervals for 60 min. The diameters of edema in the halothane group lessened more than those in the oxygen group at 1 and 24 hr in each following of the injection (p<0.05). The rats pre-administered with oxygen or halothane were similar appearances in nociceptive behaviors. It suggests that halothane anesthesia might inhibit slightly the inflammatory reaction with the formalin-induced edema but might not inhibit the formalin-induced pain behavior in the event of pre-administration halothane 24 hr earlier before the formalin test of rat.

Nose neoplasms refer to any type of abnormal growth or tumor that develops in the nose or nasal passages. These tumors can be benign (non-cancerous) or malignant (cancerous), and they can affect people of all ages.

Types of Nose Neoplasms[2]

There are several types of nose neoplasms, including:

1. Nasal polyps: These are benign growths that can occur in the nasal passages and are usually associated with allergies or chronic sinus infections.
2. Nasal carcinoma: This is a type of cancer that affects the nasal passages and can be either benign or malignant.
3. Esthesioneuroblastoma: This is a rare type of cancer that occurs in the nasal passages and is usually found in children.
4. Adenocarcinoma: This is a type of cancer that affects the glandular tissue in the nose and can be either benign or malignant.
5. Squamous cell carcinoma: This is a type of cancer that affects the squamous cells in the skin and mucous membranes of the nose.

Symptoms of Nose Neoplasms[3]

The symptoms of nose neoplasms can vary depending on the type and location of the tumor. Some common symptoms include:

1. Nasal congestion or blockage
2. Nasal discharge or bleeding
3. Loss of sense of smell or taste
4. Headaches
5. Sinus infections or other respiratory problems
6. Swelling or lumps in the nose or face
7. Difficulty breathing through the nose

Diagnosis and Treatment of Nose Neoplasms[4]

The diagnosis of nose neoplasms typically involves a combination of physical examination, imaging tests (such as CT scans or MRI), and biopsies. Treatment depends on the type and location of the tumor, and may involve surgery, radiation therapy, chemotherapy, or a combination of these. Some common treatment options include:

1. Surgical excision: This involves removing the tumor and any affected tissue through a surgical procedure.
2. Radiation therapy: This involves using high-energy beams to kill cancer cells.
3. Chemotherapy: This involves using drugs to kill cancer cells.
4. Laser therapy: This involves using a laser to remove or destroy the tumor.
5. Cryotherapy: This involves using extreme cold to destroy the tumor.

Prognosis and Follow-Up Care[5]

The prognosis for nose neoplasms depends on the type and location of the tumor, as well as the stage of the cancer. In general, early detection and treatment improve the chances of a successful outcome. Follow-up care is important to monitor the patient's condition and detect any recurrences or complications. Some common follow-up procedures include:

1. Regular check-ups with an otolaryngologist (ENT specialist)
2. Imaging tests (such as CT scans or MRI) to monitor the tumor and detect any recurrences
3. Biopsies to evaluate any changes in the tumor
4. Treatment of any complications that may arise, such as bleeding or infection.

Lifestyle Changes and Home Remedies[6]

There are several lifestyle changes and home remedies that can help improve the symptoms and quality of life for patients with nose neoplasms. These include:

1. Maintaining good hygiene, such as regularly washing the hands and avoiding close contact with others.
2. Avoiding smoking and other tobacco products, which can exacerbate the symptoms of nose cancer.
3. Using saline nasal sprays or drops to keep the nasal passages moist and reduce congestion.
4. Applying warm compresses to the affected area to help reduce swelling and ease pain.
5. Using over-the-counter pain medications, such as acetaminophen or ibuprofen, to manage symptoms.
6. Avoiding blowing the nose, which can dislodge the tumor and cause bleeding.
7. Avoiding exposure to pollutants and allergens that can irritate the nasal passages.
8. Using a humidifier to add moisture to the air and relieve dryness and congestion in the nasal passages.
9. Practicing good sleep hygiene, such as avoiding caffeine and electronic screens before bedtime and creating a relaxing sleep environment.
10. Managing stress through relaxation techniques, such as meditation or deep breathing exercises.

Nose neoplasms can have a significant impact on a person's quality of life, but with proper diagnosis and treatment, many patients can experience improved symptoms and outcomes. It is important for patients to work closely with their healthcare providers to develop a personalized treatment plan that addresses their specific needs and goals. Additionally, lifestyle changes and home remedies can help improve symptoms and quality of life for patients with nose neoplasms.

1. Asbestosis: a lung disease caused by inhaling asbestos fibers.
2. Carpal tunnel syndrome: a nerve disorder caused by repetitive motion and pressure on the wrist.
3. Mesothelioma: a type of cancer caused by exposure to asbestos.
4. Pneumoconiosis: a lung disease caused by inhaling dust from mining or other heavy industries.
5. Repetitive strain injuries: injuries caused by repetitive motions, such as typing or using vibrating tools.
6. Skin conditions: such as skin irritation and dermatitis caused by exposure to chemicals or other substances in the workplace.
7. Hearing loss: caused by loud noises in the workplace.
8. Back injuries: caused by lifting, bending, or twisting.
9. Respiratory problems: such as asthma and other breathing difficulties caused by exposure to chemicals or dust in the workplace.
10. Cancer: caused by exposure to carcinogens such as radiation, certain chemicals, or heavy metals in the workplace.

Occupational diseases can be difficult to diagnose and treat, as they often develop gradually over time and may not be immediately attributed to the work environment. In some cases, these diseases may not appear until years after exposure has ended. It is important for workers to be aware of the potential health risks associated with their job and take steps to protect themselves, such as wearing protective gear, following safety protocols, and seeking regular medical check-ups. Employers also have a responsibility to provide a safe work environment and follow strict regulations to prevent the spread of occupational diseases.
