AI Article Synopsis
Article Abstract
Angiogenesis is the focus of therapeutic efforts to promote new vessel development in damaged tissues. Conversely, inhibiting endothelial cell growth and survival is a strategy to treat various proliferative diseases. Much evidence indicates that VEGF is a key mediator of angiogenesis. Recently, a novel angiogenic mitogen with tissue-specific expression and target selectivity was characterized. Human endocrine gland derived vascular endothelial growth factor (EG-VEGF) is selectively expressed in steroidogenic glands and promotes growth of endocrine gland endothelium. The identification of tissue-selective angiogenic factors raises the possibility that other secreted molecules in this class exist. The potential advantage of tissue-specific angiogenic therapeutics may be the reduction of systemic side effects. Additionally, these peptides or their receptors may be attractive targets for inhibition in several disorders.

Noncoding satellite DNA repeats are abundant at the pericentromeric heterochromatin of eukaryotic chromosomes. During interphase, sequence-specific DNA-binding proteins cluster these repeats from multiple chromosomes into nuclear foci known as chromocenters. Despite the pivotal role of chromocenters in cellular processes like genome encapsulation and gene repression, the associated proteins remain incompletely characterized.

The current study investigated the effect of a single administration of human chorionic gonadotropin hormone (hCG) and its nanoparticles (NPs) on testicular hemodynamics using Doppler ultrasonography, testicular volume, testicular echotexture (PIX), and circulating testosterone and nitric oxide (NO) in pubescent goat bucks during summer months. Fifteen Baladi goats were divided into three groups (5 in each) and subjected to a single intramuscular administration of one ml of physiological saline ( control group), one ml containing 500 IU of hCG (hCG group) or one ml containing 125 IU of hCG NPs (hCG NPs group). Testicular hemodynamics assessment was done just before administration (0 h), and at 2, 4, 6, 24, and daily till 7 days after administration.

Unlabelled: This study aims to determine the incidence, clinical course, and risk factors of hypothyroidism following cardiac catheter (CC) in infants with congenital heart diseases (CHD). This prospective study involved 115 patients with CHD, all aged 3 years or younger, who underwent CC, as well as 100 healthy age- and sex-matched controls. Baseline thyroid function tests (TFTs) were conducted for both the patients and controls.

Ovarian ischemia is a pathological condition that usually occurs due to ovarian torsion, resulting in the interruption of blood supply to the ovaries and oxygen deficiency. Silymarin (SLM) is a flavonoid complex of plant origin with pharmacological properties such as antioxidant, anti-inflammatory, and antiapoptotic effects. In this study, we investigated the effects of SLM through different pathways in rats subjected to experimental ovarian ischemia/reperfusion (I/R).

Materials And Methods: Using various databases and tools, we identified 155 active compounds within BSTSD's herbal components. Key compounds such as eriodictyol and β-sitosterol were noted for their significant anti-inflammatory, antioxidant, and immunomodulatory effects, which are crucial for promoting fracture healing.
