The effectiveness of boron-doped diamond (BDD) and titanium metal-mixed oxides (Ti/MMO: Ti/RuO-TiO and Ti/RuO-IrO-Pt) anodes to treat cheese whey wastewater (CWW) by electrochemical oxidation (EO) was evaluated. The results show that EO with BDD is effective in the removal of organic compounds. Conversely, Ti/MMO anodes exhibit higher removals of nitrogenated compounds.

Ixodid ticks are important disease vectors that significantly impact animal health and cause considerable economic losses, particularly in tropical and subtropical countries. The aim of the present study was to determine the identity, seasonal distribution, and preferred attachment sites of adult ixodid tick species of cattle in four municipalities (Aïn El Hadid, Sidi Bakhti, Mechraa Safa, and Sidi Hosni) of the Province of Tiaret (north-west Algeria) between May 2022 and May 2023. A total of 317 cattle were randomly selected and examined for tick infestation; 108 (34.

Background: Obesity is attributed to a combination of factors such as lifestyle, environmental influences, and genetic background. Nowadays, the issue of obesity has grown to an epidemic scale. Environmental changes, having contributed to the sharp rise in obesity prevalence, are not the only contributing etiologic factors.

Introduction: The aim of this observational study was to investigate the risk factors of a failed first attempt at pediatric central venous catheter (CVC) placement and its impact on CVC-related morbidity.

Materials And Methods: In this prospective observational study, we included 3-month-to 5-year-old children proposed for infraclavicular subclavian vein catheterization consecutively sing the anatomic landmark technique. Patients were divided into two groups: group 1 included single-attempt catheter placements, and Group 2 included failed first attempts at catheter placement.

Objective: The purpose of this study is to compare the surgical outcomes of open appendectomy (OA) and laparoscopic appendectomy (LA) for pediatric acute appendicitis in order to guide its future management.

Materials And Methods: We conducted a retrospective study including all children under the age of 14 years, who underwent appendectomy for acute appendicitis, during a period of 6 years (2013-2018). We divided our patients in two groups based on the surgical modality: the laparoscopic and open group.

In this paper, filamentous fungi have been used as biotemplates to integrate gold nanoparticles (Au-NPs) into the cell wall. A new chemical mechanism has been proposed to elucidate the assimilation of Au-NPs by fungi, considering the ionic current that arises in the function of fungal metabolism. After biological components were eliminated, mycelium-like gold microtubes have been obtained using different fungal species as precursors.

Objective: To examine outcomes and associated risk factors for children who undergo surgery for lung hydatidosis (LH).

Study Design: Through a retrospective and analytical-aim-study, over a period of 35 years in 2 surgical departments, we reported all operative cases for LH in children, regardless of cyst number, location, and aspect. Univariate and multivariable analyses were used to assess variables potentially predictive of postoperative morbidity.

Objective: The aim of the study was to assess the survival rates and surgery-related toxicity in patients with locally advanced squamous cell vulvar cancer (LAVC) managed by upfront chemoradiation (CRT) with/without following by surgery. CRT is the primary treatment for patients with unresectable locally advanced squamous cell vulvar carcinoma (LAVC), followed by surgery in case of residual tumor.

Methods: Patients with AJCC stage II-IV squamous cell vulvar carcinoma referred to Gynecologic Oncology Unit at Fondazione Policlinico Universitario Agostino Gemelli I.

Self-doped CuS nanoparticles (NPs) were successfully synthesized via microwave-assisted polyol process to act as co-catalysts to TiO nanofiber (NF)-based photoanodes to achieve higher photocurrents on visible light-assisted water electrolysis. The strategy adopted to perform the copper cation sulfidation in polyol allowed us to overcome the challenges associated with the copper cation reactivity and particle size control. The impregnation of the CuS NPs on TiO NFs synthesized via hydrothermal corrosion of a metallic Ti support resulted in composites with increased visible and near-infrared light absorption compared to the pristine support.

Current biomedical imaging techniques are vital for the diagnosis of various diseases. They are related to the development of multimodal probes encompassing all the functionalities required for comprehensive imaging. In this context, we applied a simple and reproducible wet synthesis route to produce such probes.

Article Synopsis
  • Aotearoa New Zealand has seen a rise in invasive group A streptococcal (iGAS) infections since October 2022, especially among children and marginalized communities like Māori and Pacific peoples.
  • The study analyzed national surveillance data from 2017 to 2023, finding that iGAS infections decreased during COVID-19 restrictions and surged once those restrictions were lifted, showing a moderate correlation with acute respiratory infections.
  • The trends in New Zealand reflect a similar global increase in iGAS, highlighting the need for improved surveillance and response strategies as iGAS will become notifiable in late 2024.

Background: Difficult airway management is one of the main challenges in paediatric anaesthesia, particularly in low- and middle-income countries.

Aims: The aim of this study was to investigate the main predictors of difficult paediatric intubation.

Methods: In this observational study, we included all children aged less than five years undergoing intra-abdominal surgery with endotracheal intubation.

  • Perineal ectopic testis (PET) is a rare condition where the testis is misplaced, often diagnosed through physical exams revealing an empty scrotum alongside discomfort in the perineal area, especially when sitting.
  • In two pediatric cases, children experienced perineal discomfort leading to difficulties in sitting, prompting surgical intervention (orchidopexy) to correct the testis position, with successful outcomes and no complications.
  • Early diagnosis and treatment are vital in PET to ensure proper testicular function, with symptoms of discomfort serving as important indicators for further examination in young patients.

Background And Importance: Urethral Prolapse (UP), first described by Solinger in 1732, is a rare condition characterized by the circular protrusion of the distal urethral mucosa through the external meatus, forming a hemorrhagic, sensitive vulvar mass. This condition is most commonly observed in prepubertal black females. This case report details the clinical manifestations and surgical management of UP in three young girls.

The traditional homogenous and heterogenous Fenton reactions have frequently been restrained by the lower production of Fe ions, which significantly obstructs the generation of hydroxyl radicals from the decomposition of HO. Thus, we introduce novel photo-Fenton-assisted plasmonic heterojunctions by immobilizing FeO and Bi nanoparticles onto 3D SbO via co-precipitation and solvothermal approaches. The ternary SbO/FeO/Bi composites offered boosted photo-Fenton behavior with a metronidazole (MNZ) oxidation efficiency of 92% within 60 min.

The polyol synthesis of CoO nanoparticles (NPs) is typically conducted by dissolving and heating cobalt acetate tetrahydrate and water in diethylene glycol (DEG). This process yields aggregates of approximately 100 nm made of partially aligned primary crystals. However, the synthesis demands careful temperature control to allow the nucleation of CoO while simultaneously preventing reduction, caused by the activity of DEG.
