Institute of Chemical Sciences, University of Peshawar, Peshawar 25120, Khyber Pakhtunkhwa, Pakistan.

This manuscript serves as a follow-up to our previous work, "Bibliometric Analysis: A Few Suggestions," where we highlighted key aspects of bibliometric research and offered recommendations for improving its rigor. In this draft, we expand on those ideas and provide additional suggestions aimed at enhancing the depth and scope of bibliometric analysis. By analyzing 36 randomly selected bibliometric studies, we identified common practices and gaps in the field, which informed the inclusion of new recommendations not covered in our earlier paper.

The tumor distance to the main hepatic vessels is a predictor of recurrence-free survival and overall survival in hepatocellular cancer.

Langenbecks Arch Surg

January 2025

Department of Surgery, Medical Faculty Mannheim, Universitätsmedizin Mannheim, Heidelberg University, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Germany.

Introduction: The impact of the distance of the tumor from the main hepatic vessels (DTV), such as the Glissonean pedicle or hepatic veins, on oncological outcomes for Hepatocellular carcinoma (HCC) patients is relatively understudied. Therefore, the objective of this study was to explore the correlation between DTV and survival in patients with HCC after curative hepatic resection.

Methods: Consecutive patients who underwent curative-intent liver surgery for HCC between April 2018 and May 2023 were identified from a prospective database.

Regulation of INPP5E in Ciliogenesis, Development, and Disease.

Int J Biol Sci

January 2025

Department of Basic & Translational Sciences, School of Dental Medicine, University of Pennsylvania, USA.

Inositol polyphosphate-5-phosphatase E (INPP5E) is a 5-phosphatase critically involved in diverse physiological processes, including embryonic development, neurological function, immune regulation, hemopoietic cell dynamics, and macrophage proliferation, differentiation, and phagocytosis. Mutations in cause Joubert and Meckel-Gruber syndromes in humans; these are characterized by brain malformations, microphthalmia, situs inversus, skeletal abnormalities, and polydactyly. Recent studies have demonstrated the key role of INPP5E in governing intracellular processes like endocytosis, exocytosis, vesicular trafficking, and membrane dynamics.

Methanol is a widely used industrial and household alcohol that poses significant health risks upon exposure. Despite its extensive use, methanol poisoning remains a critical public health concern globally, often resulting from accidental or intentional ingestion and outbreaks linked to contaminated beverages. Methanol toxicity stems from its metabolic conversion to formaldehyde and formic acid, leading to severe metabolic acidosis and multiorgan damage, including profound CNS effects and visual impairments.

The antioxidant/antiapoptotic features of dapagliflozin (DPG) have mediated its beneficial actions against several experimental models. However, no studies have been conducted to determine whether DPG mitigates the renal injury triggered by cadmium (Cd). Herein, DPG was studied for its potential to attenuate kidney damage in Cd-intoxicated rats, as well as to unravel the mechanisms involving oxidative events, autophagy, and apoptosis.

Vitiligo detection capabilities of 1D photonic crystal biosensing design.

Sci Rep

January 2025

Physics Department, Faculty of Sciences, TH-PPM Group, Beni-Suef University, Beni Suef, 62514, Egypt.

This theoretical work focuses on the application of Tamm resonance-based biosensing using a one-dimensional photonic crystal for detecting skin vitiligo, a condition caused by the loss of pigment in the body. This biosensor utilizes the interaction of light with the photonic structure to identify the specific biomarkers associated with vitiligo. The proposed structure is composed of prism/Ag/skin-sample/(GaP/PS)/glass.

A Schiff base of Chitosan was prepared by condensing of the Chitosan (CS) with six aromatic aldehydes and confirmed by FT-IR, NMR, XRD, TGA, and DSC. XRD results showed the disappeared of peaks at 2θ = 10° for CS and appeared one peaks at around 2θ of 23° for Schiff bases, while TGA was demonstrated that the thermal stability of CS has improved after the modification with the corresponding aldehyde. Also, DSC shows endothermal peak of CS at 100 °C due to the loss of water and second thermal event related to the decomposition of amine units with an exothermic peak at 295 °C, while Schiff bases shows endothermal peak around 70-95 °C which is related to the loss of water for all samples and the second exothermic peak around 260-280 °C is related to the decomposition of the amine group in the polymer units.
