Article Synopsis
  • The structures of the anticancer drugs satraplatin and picoplatin were optimized, and theoretical studies using Density Functional Theory (DFT) revealed their low energy gap and high chemical softness, indicating stability and reactivity.
  • DFT analysis and molecular docking demonstrated that satraplatin had a stronger binding affinity to cancer DNA than picoplatin, with binding energies of -5.06 kcal/mol and -2.69 kcal/mol, respectively.
  • The results suggest that both compounds have favorable structural properties and reactivity, making them suitable for targeting biological molecules in cancer treatment.

Background: Spermatogonial stem cells (SSCs) were considered to be stem cells with limited potencies due to their existence in adult organisms. However, the production of spermatogonial stem cell colonies with broader differentiation capabilities in primary germ cell cultures from mice of select genetic backgrounds (C57BL6/Tg14, ddY, FVB and 129/Ola) indicated that SSCs from these strains were pluripotent.

Methods: We established primary cultures of SSCs from neonatal and adult Swiss 3T3 Albino mice.

Modern hip arthroplasty still faces the issue of wear in the articulating surface and wear induced debris. Thus, the design of hip implant is highly important for its longevity. Experimental demonstration of wear in hip implant involves both time and cost and, in this regard, finite element analysis acts as a suitable alternative.

The optimized structures and theoretical studies of metal based anticancer drugs Nedaplatin (cis-Diammine glycolato platinum) (CDGP) and Oxaliplatin (Diaminocyclohexane oxalatoplatinum) (DCOP) structures by Density Functional Theory (DFT) method at the B3LYP level with LANL2DZ was applied to investigate the spectroscopic, structural optical properties, conducting properties for the chosen materials, Band Gap was predicted with the help of HOMO-LUMO values. From the calculated parameters of the title compounds CDGP and DCOP shows DCOP found to be highly reactive metal complexed anticancer drug over CDGP. On calculating the site of the lowest binding energy a receptor active site with ligand is done by Ligand-protein docking process.

Background: A hemodynamically significant arteriovenous fistula (AVF) in end-stage kidney disease (ESKD) causes a high flow state, resulting in pathologic cardiovascular remodeling, and deserves timely clinical recognition.

Case: A 55-year-old woman with history of ESKD with deceased donor kidney transplant with failing graft function and baseline creatinine of 2.8 mg/dl presented to the clinic with nocturnal cough, orthopnea, dyspnea on exertion and pedal edema.

There is limited information regarding the prevalence of extracranial carotid atherosclerosis in the patients with coronary artery disease (CAD) undergoing coronary artery bypass graft (CABG) surgery in South East Asia. The primary objective was to assess the prevalence of extracranial carotid stenosis, raised carotid intima media thickness (CIMT), and plaques in the patients with CAD undergoing elective CABG. The secondary objective was to evaluate the risk factors for extracranial carotid atherosclerosis.

Context: Clinical study of breast cancer patients in Chicago, IL, USA.

Objective: Ascertain the utility of measurements of single-strand breaks (SSB) in DNA for assessment of breast cancer risk.

Methods: Fine-needle aspirates of the breast, SSB by nick translation, percent breast density (PBD), Gail model risk, cumulative methylation index (CMI), enzymes of DNA repair and tissue antioxidants.

Scimitar syndrome is a rare congenital anomaly characterized by anomalous pulmonary venous drainage to the inferior vena cava, causing a left-to-right shunt. Six patients with scimitar syndrome were diagnosed in our hospital between 2002 and 2008. There were 4 girls and 2 boys; 4 < 5 kg in weight, 2 < 8 kg in weight.

Background: Few studies have examined the possible role of blood pressure (BP), independent of acute rejection and graft function, on outcomes after kidney transplantation.

Methods: We investigated the prevalence, treatment, control, and clinical correlates of hypertension and its association with outcomes, using multivariate analyses with time-dependent covariates, in a retrospective cohort of 1,666 kidney transplant recipients.

Results: Hypertension was common, and its control was poor.

Dyslipidemias are common in patients with chronic kidney disease. The causes vary with the stage of kidney disease, the degree of proteinuria, and the modality of end-stage renal disease treatment. Dyslipidemias have been associated with kidney disease progression, and a number of small, randomized, controlled trials of lipid-lowering agents have been conducted.

Cyclosporine is used widely as an immunosuppressant in transplant recipients and for various autoimmune diseases. In some cases, these patients require therapeutic plasma exchange (TPE). Cyclosporine is known to be highly bound to lipoproteins, and their removal by TPE would be expected to have an impact on drug dosing.
