Objective: To analyze the causes, clinical features and t r ea tment ou tcomes in pa t i en t s w i th nonobstructive azoospermia (NOA) and different severity of hypospermatogenesis (HS). Methods: This is a retrospective study from our reproductive clinic. Data of history, physical findings, serum hormone profiles and genetic studies were collected. The severity of HS was subdivided into three ...

A modified form of heparan sulfate (HS) known as 3-O-sulfated heparan sulfate (3-OS HS) generates fusion receptor for herpes simplex virus (HSV) entry and spread. Primary cultures of corneal fibroblasts derived from human eye donors have shown the clinical significance of this receptor during HSV corneal infection. 3-OS HS- is a product of a rare enzymatic modification at C3 position of glucosa...

BACKGROUND Hippocampal sclerosis (HS) is a neuropathological finding that frequently occurs with pathologies, such as Alzheimer's disease (AD). Prevalence estimates of HS in autopsy-confirmed dementia samples have varied between 0.4% and 24.5%. However, the prevalence of HS within other pathologic groups has not been well characterized. METHODS Utilizing a sample of 910 prospectively followed...

Detailed analysis of various heparan sulfate (HS) species is seriously hampered by a lack of appropriate tools, such as antibodies. We adopted phage display technology to generate anti-HS antibodies. A "single pot" semisynthetic human antibody phage display library was subjected to four rounds of selection on HS from bovine kidney using panning methodology. Three different phage clones expressi...

Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in solution, zeolites HS and P are more stable than zeolites X and Y respectively

Background: The process of inflammation induces hepatic synthesis of various acute phase proteins such as high sensitivity C-reactive protein (hs-CRP) which is believed to play a role in insulin resistance. Higher incidence of type-2 diabetes mellitus has been observed with high levels of hs-CRP. Objectives: The present case control study was under taken to 1. Find the serum hs-CRP levels in ty...

N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) is a natural tetrapeptide with anti-inflammatory and antifibrotic properties. Its effect on salt-sensitive (SS) hypertension is unknown. We hypothesized that in Dahl SS rats on high-salt (HS) diet, Ac-SDKP prevents loss of nephrin expression and renal immune cell infiltration, leading to a decrease in albuminuria, renal inflammation, fibrosis, and...

BACKGROUND The time course and mechanisms of altered mechanoenergetics and depressed cross-bridge cycling in hypertrophied and failing myocardium are uncertain. METHODS AND RESULTS We studied mechanoenergetics in Dahl salt-sensitive (DS) rats fed high-salt diet (HS) for 6 (HS-6) and 12 (HS-12) weeks to produce compensated hypertrophy and failure. The slope of the end-systolic pressure-volume ...

Heparan sulfate (HS) proteoglycans comprising HS glycosaminoglycan chains (HS-chains) and core proteins function in the membrane and extracellular matrix (ECM) as co-receptors for growth factors; i.e., they modulate activity of signaling factors via controlling their extracellular stabilization and movement. However, precise mechanisms by which HS-chains regulate complex mammalian morphogenetic...

BACKGROUND Definitive diagnosis of histiocytic sarcoma (HS) in dogs is relatively difficult by conventional histopathological examination because objective features of HS are not well defined. HYPOTHESIS Quantitative analysis of mRNA expression of selected cellular surface antigens (SAs) specific to HS in dogs can facilitate objective and rapid diagnosis. ANIMALS Dogs with HS (n = 30) and d...
