Placental morphology and cellular arrangement are altered in maternal diseases such as preeclampsia (PE) in which oxygen delivery from the mother to the fetus is greatly disturbed, ultimately resulting in cellular oxidative stress. The present study was conducted at the Department of Anatomy and included 112 placentas (56 each from mothers with and without PE [controls]) collected at the Department of Obstetrics and Gynecology. A histological study was performed using hematoxylin and eosin staining. The morphology of stem and terminal villi (TV) was studied, and the surface area and diameter of TV and capillaries were measured. The gross placental morphometrical study revealed that the mean placental weight, thickness, diameter, and surface area were significantly lower in placentas with PE than in controls. The histomorphometrical findings of the villous surface area and diameter were lower in placentas with PE, whereas the TV density was higher in placentas with PE than in controls, and the differences were significant (P<0.0001). In these TV, the diameter and density of fetal blood vessels of placentas with PE were significantly lower than those of controls (P<0.05). In conclusion, the both morphological and histological changes in PE placentas are indicative of the pathogenesis of maternal and fetal morbidity and mortality in women with PE. The observed and comparative histomorphometrical changes indicate a decline in all aspects of the PE placenta, except the number of TV.

The vasculosyncytial membrane (VSM), primary site of fetomaternal exchange is formed when syncytiotrophoblast surrounds the terminal villi and make a close contact with capillaries. Some syncytiotrophoblast forms thin single layer of villous and some syncytial nuclei become piled up to form the syncytial knots (SKs). Undoubtedly there is a clear-cut inverse relation between villous VSM and fetal hypoxia. In preeclampsia (PE) the hypoxia injury disrupts the syncytial architecture which in turn initiates other complications of PE. Present study was designed to observe the morphological and histomorphometric features of 84 placentas from control and PE (42 each) collected from Department of Obstetrics and Gynecology. Neonatal weight and placental weight were reduced in PE than the controls but the feto-placental index did not differ. The SK density and VSM thickness was found to be increased and was statistically significant in PE cases. In relation to SKs, the VSM thickness was twofold increased than the controls and was statistically significant. The SKs in the present study were classified as type-1, 2a, 2b, and 3. Type 1 was found to be 62% in control and 47% in PE, type 2a and 2b were 38% in control and 37% in PE, and type 3 was in 8% of PE cases. All the parameters of present study reveal the adverse effects of PE influencing on both morphological and microscopical features of the placenta resulting in fetal hypoxia.

<b>AIMb>To determine if Yq microdeletion frequency and loci of deletion are similar in two tissues (blood and sperm) of different embryological origin.
<b>METHODSb>The present study included 52 infertile oligozoospermic cases. In each case, DNA was isolated from blood and sperms and polymerase chain reaction (PCR) microdeletion analysis was done from genomic DNA isolated from both the tissues. The PCR products were analyzed on a 1.8% agarose gel. PCR amplifications found to be negative were repeated at least three times to confirm the deletion of a given marker.
<b>RESULTSb>Only 1 case harbored microdeletion in blood DNA, whereas 4 cases harbored microdeletion in sperm DNA.
<b>CONCLUSIONb>The frequency of Yq microdeletions is higher in germ cells as compared to blood. As the majority of infertile couples opt for assisted reproduction procreation techniques (ART), Yq microdeletion screening from germ cells is important to understand the genetic basis of infertility, to provide comprehensive counseling and most adapted therapeutics to the infertile couple.

The WHO reports that billions of people and animals in tropical and subtropical regions are affected by helminthiasis as neglected tropical disease. It is predominant in underdeveloped areas; nevertheless, the increase in the number of travelers and migrants has made this infection more common. The current mass drug treatment produces severe side effects and many strains of helminths are resistant to them. None of the chemotherapeutic drugs meets the ideal requirements of anthelmintics, such as broad spectrum of activity, single dose cure, free from side effect and cost-effectiveness. Today, many researchers are screening the traditional herbal system in search of the anthelmintic herbal constituents which overcome all the problems of synthetic drugs. Several researchers proclaim anthelmintic activity of herbal medicines by using different experimental models. The present review demonstrates natural product drug discovery, outlining potential of herbal constituents from natural sources as natural leads against helminthiasis.

The common femoral artery (CFA) typically gives rise to its superficial and deep branches, with the deep femoral artery (DFA) being the largest and most substantial of these branches. This case study presents a rare variation of the DFA characterized by an unusual branching pattern and its specific relationship with the femoral vein within the subinguinal region. In nutshell, the DFA and the medial femoral circumflex artery shared a common origin from the medial aspect of the CFA. The DFA assumed an unusual course, initially passing anterior to the femoral vein above the saphenofemoral junction, followed by a spiraling trajectory around the medial aspect of the femoral vein before running posteriorly. The embryological origins and clinical implications of this anatomical variation are thoroughly examined. This unusual vascular relationship in the subinguinal region may potentially result in arterial injury during femoral vein cannulation or formation of arteriovenous fistula after the procedure.
