Article Synopsis
  • Chloroquine (CQ) has been studied as a potential treatment for cancer, specifically colorectal cancer, by examining its effects on HCT-116 cells and its mechanism of action.
  • CQ was found to inhibit the growth and survival of these cancer cells under hypoxic conditions by reducing both glycolytic capacity and NAD production through the inhibition of the PDK1 protein.
  • The study revealed that CQ induces structural changes in PDK1, leading to its destabilization and increased degradation, which subsequently causes mitochondrial damage, excessive ROS production, and eventually triggers apoptosis in cancer cells.

Background: Our objectives were to determine 1) the prevalence and description of placental pathologic lesions in pregnancies complicated by SARS-CoV-2 infection compared to healthy controls and 2) whether the prevalence and/ or pattern of placental pathologic lesions differed in the few neonates who tested positive for SARS-CoV-2 in the first 48 hours of life at a busy urban county hospital.

Methods: This study included all pregnant mothers who tested positive for SARS-CoV-2 and delivered at our institution from March 2020 to June 2021, while control placentas were collected from term pregnancies without complications.

Results: Approximately 90% (n = 380/425) of placentas from pregnancies complicated by SARS-CoV-2 infections had placental pathologic lesions, compared to 32% (n = 16/50) of controls.

Article Synopsis
  • The study assesses water quality in 41 surface water bodies in Bengaluru, revealing that over half exceed WHO limits for key indicators like pH and total dissolved solids, with various toxic elements also present in concerning concentrations.
  • Toxic element pollution primarily stems from industrial activities, traffic, and natural geological sources, leading to varying degrees of contamination; 25% of the waters have high contamination levels, particularly in specific lakes and drainage systems.
  • The contamination poses significant health risks, with medium to high non-carcinogenic risks for both adults and children, and a high carcinogenic risk, as polluted water channels lead to larger rivers affecting neighboring states and ecosystems.

Background: Hypertension is a leading contributor to cardiovascular disorders globally. There has been a recent upsurge in non-pharmacological management involving mindfulness-based meditation (MBM) in lowering blood pressure (BP) among the hypertensive population; however, the level of supportive evidence among patients primarily diagnosed with hypertension remain limited. Therefore, this systematic review aimed to synthesize the evidence of randomized controlled trials (RCTs) on the effect of MBM on BP explicitly in adults primarily diagnosed with elevated blood pressure or hypertension.

Article Synopsis
  • Neonates with congenital heart disease (CHD) often have smaller brain volumes at birth, possibly due to placental issues impacting brain development.
  • This study analyzed infants with significant heart defects who required surgery within their first year, measuring blood flow in key brain arteries shortly after birth.
  • Results showed that CHD patients had higher blood flow resistance in their cerebral arteries compared to healthy controls, but the placental vascular problems didn’t seem to directly affect this resistance in most cases.

Background: Inter-alpha inhibitor proteins (IAIPs) are structurally related proteins found in the systemic circulation with immunomodulatory anti-inflammatory properties. Reduced levels are found in inflammatory related conditions including sepsis and necrotizing enterocolitis, and in neonatal rodents after exposure to hypoxia ischemia. In the current study, cord blood IAIP levels were measured in neonates with and without exposure to hypoxic-ischemic encephalopathy (HIE).

Purpose: Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4/-13, key and central drivers of type 2 inflammation in multiple diseases. This post hoc analysis of the Phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959) evaluated the efficacy of dupilumab in children aged 6 to 11 years with moderate-to-severe asthma with a type 2 inflammatory phenotype (blood eosinophil count ≥150 cells/µL or fractional exhaled nitric oxide [FeNO] ≥20 ppb) and a history of 1, 2, or ≥3 prior exacerbations. The impact of baseline type 2 biomarker levels on the efficacy of dupilumab in this population was also investigated.

Hepatocellular carcinoma (HCC) persists to be one of the most devastating and deadliest malignancies globally. Recent research into the molecular signaling networks entailed in many malignancies has given some prominent insights that can be leveraged to create molecular therapeutics for combating HCC. Therefore, in the current communication, an in-silico drug repurposing approach has been employed to target the function of PTP4A3/PRL-3 protein in HCC using antidepressants: Fluoxetine hydrochloride, Citalopram, Amitriptyline, Imipramine, and Escitalopram oxalate as the desired ligands.
