Objectives: This study aimed to validate the risk of SARS-CoV-2 infection, identify infection risk factors among air passengers subject to a 14-day mandatory quarantine, and evaluate the accuracy of mass symptom-based screening criteria at an airport.

Methods: This retrospective cohort study analyzed data from 116,004 air passengers who entered Thailand through Suvarnabhumi Airport in Bangkok from April to September 2020. The incidence of SARS-CoV-2 infection, risk characteristics, and accuracy indices of symptom-based screening were calculated.

Understanding Cryptococcus neoformans pathogenesis requires a detailed analysis of the various virulence factors that contribute to its ability to cause disease. Cyclosporine, calcineurin inhibitor, impairs C. neoformans production of a polysaccharide capsule and secretion of urease, which are critical for cryptococcal pathogenesis.

Objectives: This study aimed to identify the incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among fully vaccinated air travelers participating in an island-confined quarantine system (Phuket Sandbox Program). It also compared the differential risk of SARS-CoV-2 infection across different coronavirus disease 2019 (COVID-19) vaccines and the difference in time-to-detection periods between asymptomatic and symptomatic cases.

Methods: This retrospective cohort study determined the cumulative incidence of SARS-CoV-2 infection among 63 052 air travelers who participated in a quarantine program from July 1, 2021 to October 31, 2021.

Background: Auranofin is an approved anti-rheumatic drug that has a broad-range inhibitory action against several microorganisms, including human pathogenic fungi. The auranofin activity against Histoplasma capsulatum, the dimorphic fungus that causes histoplasmosis, has not been properly addressed. Since there are few therapeutic options for this life-threatening systemic mycosis, this study evaluated the effects of auranofin on H.

Estrogens exert beneficial metabolic effects by reducing food intake and enhancing energy expenditure through both central and peripheral mechanisms. The decrease of estrogen, as occurs in ovariectomy (OVX), leads to metabolic disturbances, such as increased body weight, adipose tissue mass, basal blood glucose, and impaired glucose tolerance. These effects can be reversed by reintroducing estrogen.

Pelgipeptins, tridecaptins, and elgicins are among the antimicrobials produced by Paenibacillus elgii. Growth in complex media is commonly applied to obtain lipopeptides from culture's supernatant, but it requires further purification. This study aimed to improve the yield of pelgipeptins and tridecaptins using chemically defined media.

Article Synopsis
  • Leishmaniases, including the severe visceral leishmaniasis (VL), are neglected infectious diseases primarily found in the Americas, particularly in Brazil, which accounts for a significant proportion of cases.
  • The paper presents three cases of VL co-infected with HIV, where patients showed skin lesions similar to para-kala-azar dermal leishmaniasis, highlighting severe symptoms like fever and organ enlargement.
  • The study emphasizes the need for effective follow-up and preventive measures in VL patients to improve treatment outcomes and provides valuable insights into managing para-KDL cases in Brazil.

Orthodontic tooth movement (OTM) represents a dynamic process in which the alveolar bone undergoes resorption at compression sites and deposition at tension sites, orchestrated by osteoclasts and osteoblasts, respectively. This mechanism serves as a valuable model for studying various aspects of bone adaptation, including root resorption and the cellular response to mechanical force stimuli. The protocol outlined here offers a straightforward approach to investigate OTM, establishing 0.

Epilepsy affects 1% of the global population, with approximately one-third of patients resistant to anti-seizure medications (ASMs), posing risks of physical injuries and psychological issues. Seizure prediction algorithms aim to enhance the quality of life for these individuals by providing timely alerts. This study presents a patient-specific seizure prediction algorithm applied to diverse databases (EPILEPSIAE, CHB-MIT, AES, and Epilepsy Ecosystem).

Diverse computational approaches have been widely used to assist in designing antimicrobial peptides with enhanced activities. This tactic has also been used to address the need for new treatment alternatives to combat resistant bacterial infections. Herein, we have designed eight variants from a natural peptide, pro-adrenomedullin N-terminal 20 peptide (PAMP), using an in silico pattern insertion approach, the Joker algorithm.

The incidence of invasive fungal infections caused by species is increasing, particularly in immunocompromised individuals. This increasing incidence poses a dual challenge, comprising escalating antifungal resistance and the necessity for accurate fungal identification. The complex further complicates these challenges due to limited identification tools.

Objectives: The objectives were to explore rheumatologists' current clinical screening practices of pulmonary arterial hypertension in patients with systemic sclerosis in the United Kingdom and to identify barriers to screening and consider potential solutions.

Methods: A survey of 31 questions was developed and included six sections: clinician demographics, the importance of screening, screening practices, barriers to screening, treatment and patient education. The survey was disseminated among rheumatologists working in the United Kingdom.

Article Synopsis
  • The COVID-19 pandemic exposed a global shortage of diagnostic kits, highlighting the need to optimize resource use for testing development.
  • This study focused on producing novel SARS-CoV-2 proteins using a transient expression system in Nicotiana benthamiana, employing an infectious clone vector based on pepper ringspot virus, and also evaluated antigens produced in Escherichia coli.
  • The testing showed high sensitivity (85-88%) and specificity (97.5%) across different antigens, indicating that plant-based expression systems could effectively produce recombinant antigens for diagnostics, especially in areas with limited resources.

Article Synopsis
  • Scientists are looking for new ways to treat cancer that doesn’t get stopped by drug resistance, and targeting a special process in cells called chaperone-mediated autophagy (CMA) might be a good idea.
  • CMA helps break down certain proteins that can actually help tumors grow, but it also might help cancer cells resist treatments.
  • Researchers think that by finding ways to change how CMA works, they could make cancer treatments work better and overcome drug resistance.

The objective was to evaluate the effect of detoxified castor bean replacing soybean meal in the concentrate diet or as nitrogen organic fertilizer replacing urea on intake and nutrient digestibility, blood parameters and productive performance of sheep finished on irrigated Tamani grass pasture under continuous stocking and variable stocking rate. The treatments were two concentrate diets: standard (ground corn and soybean meal) and alternative diet (ground corn and detoxified castor bean cake), and two nitrogen fertilizers: chemical (urea) and organic (fresh castor bean cake). The randomized complete block design was used in a 2 × 2 factorial arrangement with four replications (500 m² paddocks).

Objective: To analyze and compare the effects of a traditional laboratory-fabricated Hyrax expander (T-Hyrax) and two different 3D-printed Hyrax expander models relative to tension points, force distribution, and areas of concentration in the craniofacial complex during maxillary expansion using finite element analysis.

Materials And Methods: Three maxillary expanders with similar designs, but various alloys were modeled: a T-Hyrax, a fully printed Hyrax (F-Hyrax), and a hybrid printed Hyrax (H-Hyrax). The stress distributions and magnitude of displacements were assessed with a 5 mm expansion in a symmetrical finite element model.

Watermelon crinkle leaf-associated virus 1 (WCLaV-1) and WCLaV-2, both belonging to the genus Coguvirus (family Phenuiviridae), have been identified in watermelon plants in Brazil. To study tissue tropism and the potential for seed transmission of these viruses, we initially planned to produce specific antibodies. However, difficulties in isolating and propagating the virus in host plants hindered the purified virus preparations.
