Assembly of hemoglobin subunits into cooperative complexes produces a remarkable variety of architectures, ranging in oligomeric state from dimers to complexes containing 144 hemoglobin subunits. Diverse stereochemical mechanisms for modulating ligand affinity through intersubunit interactions have been revealed from studies of three distinct hemoglobin assemblages. This mechanistic diversity, which occurs between assemblies of subunits that have the same fold, provides insight into the range of regulatory strategies that are available to protein molecules.

The commercial feasibility of recombinant human Hb (rHb) as an O2 delivery pharmaceutical is limited by the production yield of holoprotein in E. coli. Currently the production ofrHb is not cost effective for use as a source in the development of third and fourth generation Hb-based oxygen carriers (HBOCs). The major problems appear to be aggregation and degradation of apoglobin at the nominal expression temperatures, 28-37° C, and the limited amount of free heme that is available for holohemoglobin assembly. One approach to solve the first problem is to inhibit apoglobin precipitation by a comparative mutagenesis strategy to improve apoglobin stability. aGlyl5 to Ala and P Glyl6 to Ala mutations have been constructed to increase the stability of the A helices of both subunits of adult human hemoglobin (HbA), based on comparison with the sequences of the more stable sperm whale hemoglobin subunits. Human fetal hemoglobin is also known to be more stable than HbA, and comparisons between human P ...

OA is the most common disease of joints in adults around the world [41], being the knee OA the most common type. About one-third of all adults have radiological signs of OA. The likelihood of developing OA increases with age. The prevalence of OA of the knee is higher among 70- to 74-year-old. Epidemiological studies have revealed that there are both endogenous and exogenous risk factors for OA. The pathogenesis of OA is characterized by the progressive destruction of articular cartilage. Many factors contribute to the overall degradation of cartilage observed in OA, either directly or indirectly by modulating anabolic factors [14]. The capacity of articular cartilage to repair is very limited, mainly because it is an avascular tissue [42]. Currently, there are no effective pharmacological treatments to treat OA although some drugs slow its progression. Surgical treatments are not a way to treat OA even so they still constitute an important tool in cartilage repair of those injuries which if not ...

These studies demonstrate for the first time that MMPs cleave PRL to generate antiangiogenic 16K-PRL. 16K-PRL blocks a variety of endothelial cell functions (Corbacho et al., 2002; Gonzalez et al., 2004; Lee et al., 2005) and inhibits angiogenesis in ocular tissues (Dueñas et al., 1999; Pan et al., 2004; Aranda et al., 2005) and in tumors (Bentzien et al., 2001; Kim et al., 2003). The specific enzymes responsible for generating 16K-PRL are largely unknown. MMPs cleave various proteins to release their bioactive forms, including the antiangiogenic fragments angiostatin (Patterson and Sang, 1997; Lijnen et al., 1998; OReilly et al., 1999) and endostatin (Lin et al., 2001). Considering that the release of antiangiogenic fragments occurs in avascular tissues such as cartilage (Pufe et al., 2004), we focused on whether chondrocyte MMPs could process PRL to 16K-PRL.. We demonstrate that MMPs produced and secreted by chondrocytes cleave PRL to generate biologically active 16K-PRL. Cleavage occurs at ...

This causes it to heal very slowly. So, you can find hyaline cartilage in the larynx and trachea in the throat portion of the body, and then also in all of the joints where the surfaces of bones are articulating each other. Cartilage is a type of connective tissue found in the body. It has a capacity for rapid interstitial and appositional growth in young and growing tissues. Three types of cartilage(hyaline cartilage, white fibrocartilage, and yellow elastic cartilage) can be distinguished on the basis of the composition and structure of their extracellular matrices, but many features of the cells and matrix are common to all three types, and these features will be considered first. This smooth, transparent, glassy type of cartilage coats the ends … This cartilage is of three types as. Articular cartilage is a physiologically non-self-renewing avascular tissue with a singular cell type, the chondrocyte, which functions as the load-bearing surface of the arthrodial joint. Cartilage is a ...

We compared population genetic structure in the αA and βA hemoglobin subunits (HBA2 and HBB) of five paired lowland and highland populations of Andean dabbling ducks to unlinked reference loci. In the hemoglobin genes, parallel amino acid replacements were overrepresented in highland lineages, and one to five derived substitutions occurred at external solvent-accessible ...

Wildlife forensic science is forensic science applied to legal issues involving wildlife. With the initiative of the Society for Wildlife Forensic Science (SWFS), the Scientific Working Group for Wildlife Forensic Sciences (SWGWILD) was formed in 2011. While animals and plants are the victims in the crimes of illegal wildlife trade and animal abuse, society also pays a heavy price when those crimes are used to fund illegal drugs, weapons and terrorism. Links between human trafficking, public corruption and illegal fishing have also been reported. The continued development and integration of wildlife forensic science as a field will be critical for successful management of the many significant social and conservation issues related to the illegal wildlife trade and wildlife law enforcement.

TY - JOUR. T1 - Inherent propensity of amnion-derived mesenchymal stem cells towards endothelial lineage. T2 - Vascularization from an avascular tissue. AU - Warrier, S.. AU - Haridas, N.. AU - Bhonde, R.. PY - 2012/10. Y1 - 2012/10. N2 - One of the most pressing problems in injury is wound healing and blood vessel formation. The amniotic membrane is important in clinical applications as it is pro-angiogenic, anti-fibrotic and anti-scarring and has low immunogenicity. In this study, we characterized amniotic membrane mesenchymal stem cells (AMMSCs) by their trademark mesenchymal stem cell (MSC) signature and profiled for embryonic pluripotency markers namely alkaline phosphatase, Oct4, Sox2, Nanog, SSEA3 and 4, and Klf4 by RT-PCR and nuclear localization of Oct4 and Nanog by immunocytochemistry. The amnion, although avascular, contains pro-angiogenic factors such as type I, III, IV and V collagen, laminin, and fibronectin in the extra cellular matrix. We, therefore, hypothesized that AMMSCs is ...

Articular hyaline cartilage is avascular tissue that provides joints with a low-friction and wear-resistant surface that provides shock absorption and high-load-bearing capabilities.4 Unfortunately, this tissue has limited regenerative capacity due to the absence of blood vessels and the low mitogenic potency of the chondrocytes. When treating cartilage defects and chondral lesions, surgeons have traditionally performed microfracture surgery to replace and create new cartilage on the articular surface.. The problem is that the cartilage created as a result of microfracture is not the same as the patients native hyaline cartilage. Studies have shown that the main tissue formed after microfracture is fibrocartilage1,2, which does not dissipate compressive force to the same degree as the original hyaline cartilage. As a result, this production of fibrocartilage may have an effect on durability and eventual failure.1 In fact, many researchers have observed that the long term results after ...

Endoscopic ventriculocisternostomy, 3rd ventriculostomy and fenestration of cysts benefit from the precise vaporization, coagulation and hemostasis by the RevoLix jr. laser. The well defined optical penetration of the RevoLix jr. laser creates a self limited laser effect as well in tissue as in liquor.

We assessed cell deformability by filtration through filters of 5-μm pore size. Whole blood, RBC, PMN, and combinations of PMN and RBC were studied. Viscometry was done on isolated RBC. Platelet-PMN interactions were assessed with monoclonal antibodies to CD41 and activated CD53 platelet receptors, and to CD66b PMN receptors. Filtration pressure (Pi) for CIS was significantly greater ...

法醫學（英語：forensic science，香港稱作法證科學，台湾稱作鑑識科學），是一種利用科學手段處理、解決與司法體系利益相關問題的科學。其主要針對刑事及民事案件。此外與法律體系相關，法醫學更多強調與運用與事實、事件、物理標的事物（例如犯罪現場、屍體）相關的學術及科學方法論及理論。關於一些在司法體系外的事物鑑定，往往也與此領域相關。 在古羅馬時期，一個罪犯通常在要法庭上面對一群公民個體進行陳述。 罪犯和逮捕方都要根據各自立場去進行辯護或陳述。其個人言辭和表達往往決定案件的結果。這一遠離導致了forensis這一詞的廣泛運用--一種司法證據形式和一類公共陳述。在現在，司法科學更多是指表達科學領域的工具學運用，而非僅僅是關於法庭的學術。 早在中國古代的秦朝，就有相關法醫學的發展。 ...
