background: the kiss peptins and its receptor g protein coupled receptor (gpr54) or kiss1 receptor system are being described as key signaling molecules for reproductive function in animal models and humans. they play essential roles in regulation of the hypothalamic- pituitary- gonadal (hpg) axis and the onset of puberty and fertility. objective: this study was performed to delineate the assoc...

introduction: the hippocampus (hip), the primary brain structure related to learning and memory, receives sparse but comprehensive dopamine innervations and contains dopamine d1/d2-like receptors. it is demonstrated that dopamine receptors in dentate gyrus (dg) region of hip have a remarkable function in spatial reward processing. much less is known about the involvement of hip and its d1/d2 do...

Background: Breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. Assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. The purpose of this study was to determine the relationship between estrogen and progesterone receptors with Her-2, Ki67, P53, and clinicopathologica...

the androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resemble males. the primary abnormality is a defective androgen receptor protein due to a mutation of the androgen receptor gene. this prevents normal androgen action and thus leads to impaired virilization. a point m...

the present study , was an attempt to develop galactosylated albumin nanoparticles of simvastatin for treatment of hypercholesterolemia. by developing the galactosylated nanoparticulated delivery the required action of drug at the target site at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur due to the distribution of the drug to t...

Skin aging results in an imbalance between synthesis and degradation of the extracellular matrix. Overproduction of degradative enzymes (MMPs) and oxygen free radicals during chronological and photo-induced aging leads a degradation of the network and elastic skin collagen. Our previous work demonstrated that a culture supernatant of gingival stem cells had anti-aging activities in vitro, ex vi...

AIMS The QT interval in the general population is a complex trait with 30-50% heritability. QT prolongation is associated with an increased risk of sudden death. A recent family-based study found an association between QT interval and the common non-synonymous Glycin 38 Serine variant (G38S, rs1805127) of the KCNE1 gene coding for the minK-potassium channel subunit. We intended to replicate thi...
