Safety and efficacy of ultrasonic dissection versus electrocautery dissection in laparoscopic cholecystectomy for acute cholecystitis: an updated systematic review and meta-analysis.

Background: Laparoscopic cholecystectomy (LC) is the current gold standard for the management of acute cholecystitis, where ultrasonic dissection and electrocautery dissection are the two primary techniques used, however, it remains uncertain which approach is safer and more effective.

Objectives: This systematic review and meta-analysis aimed to compare the clinical outcomes of ultrasonic dissection versus electrocautery dissection in LC for acute cholecystitis, particularly in operative time, hospital stay, blood loss, intraoperative and postoperative complications.

Method: A systematic literature search was conducted in PubMed (MEDLINE), Scopus, Web of Science (WOS), EMBASE, and Cochrane CENTRAL up to January 7, 2025, following PRISMA guidelines.

Using the endoscopic snare to facilitate two-port laparoscopic appendectomy.

Background: Laparoscopic appendectomy is now the gold-standard treatment for acute appendicitis, requiring three ports for a classic procedure. Recent laparoscopy improvements aim to minimize surgical trauma and improve cosmetic quality through smaller, fewer portal incisions, such as two-port laparoscopic appendectomy, resulting in reduced postoperative pain. We aimed in this study to describe a novel technique to facilitate two-port laparoscopic appendectomy using the endoscopic snare.

Speciation of vanadium and the interacted solid surface of δ-alumina adsorbent in aqueous media in presence of humic acid.

Speciation of vanadium elements in the presence of δ-alumina in aqueous media was studied to simulate the environmental impact of soil/sediment-water interacted system. Factors affecting this process are pH, presence of humic acid, and δ-alumina concentrations as an abundant sediment/soil components. Different species of both vanadium and surface of δ-alumina were deduced theoretically using MintaqA2 programme.

Association between hepatitis C virus genotype 4 and renal cell carcinoma: Molecular and virological studies.

Hepatitis C virus (HCV) is the most common infection worldwide. The correlation between HCV and renal cell carcinoma (RCC) is still mysterious. Therefore, the relationship between HCV and RCC was investigated.

Radiological assessment of different monazite grades after mechanical separation from black sand.

In Egyptian black sands, monazite is a precious mineral characterized by its composition, which includes crucial constituents such as thorium, trace amounts of uranium, and rare earth elements. It is essential to evaluate and quantify the extent of gamma-ray exposure resulting from the presence of primordial radionuclides. This necessity arises from human activities that extract and retrieve raw materials in uranium and thorium mining operations.

Morphological and glycan features of the camel oviduct epithelium.

This study describes regional differences in the oviduct of the one-humped camel (Camelus dromedarius) during the growth phase (GP) and the mature phase (MP) of the follicular wave by means of morphometry, scanning electron microscopy (SEM) and glycohistochemistry investigations. Epithelium height significantly increased in the ampulla and decreased in the isthmus passing from the GP to the MP. Under SEM, non-ciliated cells displayed apical blebs (secretory) or short microvilli.

Activated carbon from agricultural by-products for the removal of Rhodamine-B from aqueous solution.

Bagasse pith (BP) has been utilized for activated carbon preparation using H(3)PO(4) (BPH) or KOH (BPK) as a chemical activating agent followed by carbonization at 500 degrees C. The physicochemical properties of activated carbon were carried out. The effectiveness of carbon prepared in adsorption of Rhodamine B (RhB) has been studied as a function of adsorbent type, pH, particle size, agitation time, temperature, initial dye concentration, and desorption.
