The influence of microbiota on the efficacy and toxicity of immunotherapy in cancer treatment.

Immunotherapy, which uses the body's immune system to fight cancer cells, has gained attention recently as a breakthrough in cancer treatment. Although significant progress has been made, obstacles still exist since cancers are skilled at avoiding immune monitoring. The gut microbiota is being looked at more and more in modern research as a critical component in improving the results of immunotherapy.

Aptamers as an approach to targeted cancer therapy.

Conventional cancer treatments can cause serious side effects because they are not specific to cancer cells and can damage healthy cells. Aptamers often are single-stranded oligonucleotides arranged in a unique architecture, allowing them to bind specifically to target sites. This feature makes them an ideal choice for targeted therapeutics.

Chromosome conformation capture-based DNA hybridization method for chromosomal translocation screening.

DNA probes have been widely used as diagnostic tools for translocations. This study sought to design a screening tool using ssDNA probes and chromosome conformation capture (3C) library fragment hybridization. The authors focused on developing a probe for the juxtaposed region of and .

Designing a fluorescence padlock probe-based biosensor and colorimetric assay for the detection of G12D mutation.

Cell-free DNA in the plasma is known to be a potential biomarker for noninvasive diagnosis of oncogenic mutations. The authors aimed to design an optimized padlock probe-based hyperbranched rolling circle amplification biosensor to detect the  G12D mutation using fluorescence and colorimetric methods. Single-factor experiments, Plackett-Burman design and response surface methodology were applied to optimize the padlock probe-based hyperbranched rolling circle amplification reaction.

Vaccine design and delivery approaches for COVID-19.

COVID-19 is still a deadly disease that remains yet a major challenge for humans. In recent times, many large pharmaceutical and non-pharmaceutical companies have invested a lot of time and cost in fighting this disease. In this regard, today's scientific knowledge shows that designing and producing an effective vaccine is the best possible way to diminish the disease burden and dissemination or even eradicate the disease.

Approach to genetic diagnosis of inborn errors of immunity through next-generation sequencing.

Patients with inborn errors of immunity (IEI) present with a heterogeneous clinical and immunological phenotype, therefore a correct molecular diagnosis is crucial for the classification and subsequent therapeutic management. On the other hand, IEI are a group of rare congenital diseases with highly diverse features and, in most cases, an as yet unknown genetic etiology. Next generation sequencing has facilitated genetic examinations of rare inherited disorders during the recent years, thus allowing a suitable molecular diagnosis in the IEI patients.

Production of Mycophenolic Acid by a Newly Isolated Indigenous Penicillium glabrum.

Soil-occupant fungi produce a variety of mycotoxins as secondary metabolites, one of which is mycophenolic acid (MPA), an antibiotic and immunosuppressive agent. MPA is mainly produced by several species of Penicillium, especially Penicillium brevicompactum. Here, we present the first report of MPA production by a local strain belonging to Penicillium glabrum species.

Inflammation related miRNAs as an important player between obesity and cancers.

The growing trend in addition to their burden, prevalence, and death has made obesity and cancer two of the most concerning diseases worldwide. Obesity is an important risk factor for common types of cancers where the risk of some cancers is directly related to the obesity. Various inflammatory mechanisms and increased level of pro-inflammatory cytokines have been investigated in many previous studies, which play key roles in the pathophysiology and development of both of these conditions.

Evaluation and statistical optimization of a method for methylated cell-free fetal DNA extraction from maternal plasma.

Purpose: Methylated cell-free fetal DNA (cffDNA) in maternal plasma can potentially be used as a biomarker for accurate noninvasive prenatal testing (NIPT) of fetal disorders. Recovery and purification of cffDNA are key steps for downstream applications. In this study, we aimed to developed and evaluated different aspects of an optimized method and compared its efficiency with common methods used for extraction of methylated cffDNA.
