Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) is the causative pathogen of coronavirus disease-19 (COVID-19). The COVID-19 pandemic has resulted in millions of deaths and widespread socio-economic damage worldwide. Therefore, numerous studies have been conducted to identify effective measures to control the spreading of the virus.

Article Synopsis
  • Venomous snakebites can lead to serious injuries, particularly in the hand, creating challenges for surgical reconstruction.
  • A 23-year-old patient with a complex cobra-induced thumb injury was treated using a free composite anterolateral thigh (ALT) flap, which successfully covered both the extensor tendon and soft tissue in a single surgical stage.
  • This technique not only improved functionality and aesthetics of the thumb but also helped reduce recovery time, allowing for a quicker return to work, despite potential downsides like flap thickness affecting movement.

Objective: The pedicled Internal Mammary Artery Perforator (IMAP) flap is not yet a well-known technique. However, it seems practical for use in thoracic radiation-induced ulcer, especially in recurrence after the failure of convenient reconstructive techniques. This technique is applied to patients with breast hypertrophy.

Background: Reconstructing complex soft tissue defects of the finger requires both functional and aesthetic aspects. There are many free tissue transfers as suitable options for digital resurfacing. The anterolateral thigh (ALT) flap is not the first choice for reconstruction of this area because it has the disadvantage that the subcutaneous tissue is too thick; however, its use as a thinned form has yet to be described much.

Article Synopsis
  • Reconstruction of neck deformities after severe burns can be complex, and a free anterolateral thigh (ALT) perforator flap is often necessary, especially when local tissue is damaged.
  • Pre-expansion of the donor site can increase the flap’s size, with a treatment approach involving two patients who had their flaps expanded significantly over 3 to 4 months before transfer.
  • The expanded ALT flaps proved to be effective, with successful survival and improved aesthetics and function, though the method requires a two-stage procedure and has some risks such as expander displacement.

Leigh syndrome is a rare inherited, heterogeneous and progressive neurometabolic disorder that is mainly caused by specific mutations in nuclear DNA (nDNA) or mitochondrial DNA (mtDNA). The present study reported a case of childhood Leigh syndrome with a point mutation at bp 8,993 in the mitochondrial ATPase6 gene. A 21‑month‑old male child had developed epilepsy, muscular weakness and vomiting, which was accompanied by high fever.

  • Aspergillus oryzae is a safe mold used in the food industry and is also a microbial cell factory for producing proteins and enzymes.
  • Genetic manipulation of A. oryzae is challenging due to its resistance to common antifungal compounds, necessitating the use of alternative methods.
  • This study introduces binary vectors with the pyrG gene as a biochemical marker, allowing for successful expression of fluorescent proteins in A. oryzae, opening new avenues for genetic research in this important fungus.

Several studies have focused on HIV-1 protease for developing drugs for treating AIDS. Recombinant HIV-1 protease is used to screen new drugs from synthetic compounds or natural substances. However, large-scale expression and purification of this enzyme is difficult mainly because of its low expression and solubility.

Vemurafenib has recently been used as drug for treatment of melanomas with BRAFV600E mutation. Unfortunately, treatment with only vemurafenib has not been sufficiently effective, with recurrence after a short period. In this study, three vemurafenib-resistant BRAFV600E melanoma cell lines, A375PR, A375MR and SKMEL-28R, were established from the original A375P, A375M and SKMEL-28 cell lines.

Background: Wound healing has being extensively investigated over the world. Healing impairment is caused by many reasons including increasing of free-radicals-mediated damage, delaying in granulation tissue formation, reducing in angiogenesis and decreasing in collagen reorganization. These facts consequently lead to chronic wound healing.

The envelope protein VP28 of white spot syndrome virus (WSSV) is considered a candidate antigen for use in a potential vaccine to this important shrimp pathogen (the cause of white spot syndrome, WSS). Here, we used spores of Bacillus subtilis to display VP28 on the spore surface. Trials were conducted to evaluate their ability to protect shrimps against WSSV infection.

Carriers of drugs in cancer therapy are required to reduce side-effects of the drugs to normal cells. Here we constructed killed recombinant Bacillus subtilis spores (SA1) that expressed streptavidin as a chimeric fusion to the spore coat protein CotB and used the spores as bioparticle carrier. When bound with biotinylated cetuximab these spores could specifically target to the epidermal growth factor receptor on HT 29 colon cancer cells, thereby delivered paclitaxel to the cells with 4-fold higher efficiency, as indicated by fluorescent intensity of paclitaxel Oregon Green 488 bound to HT29 cells.

Proline (Pro) and Trehalose (Tre) function as compatible solutes and are upregulated in plants under abiotic stress. They play an osmoprotective role in physiological responses, enabling the plants to better tolerate the adverse effects of abiotic stress. We investigated the effect of exogenous Pro and Tre (10 mM) in seedlings of Thai aromatic rice (cv.

Triclosan was found to be a potent inhibitor of the F(H+)-ATPase of the oral pathogen Streptococcus mutans and to increase proton permeabilities of intact cells. Moreover, it acted additively with weak-acid transmembrane proton carriers, such as fluoride or sorbate, to sensitize glycolysis to acid inhibition. Even at neutral pH, triclosan could inhibit glycolysis more directly as an irreversible inhibitor of the glycolytic enzymes pyruvate kinase, lactic dehydro genase, aldolase, and the phosphoenolpyruvate:sugar phosphotransferase system (PTS).
