Respiratory samples (n = 267) from hospitalized patients with respiratory symptoms were tested by real-time PCR, viral culture, and direct immunofluorescence for respiratory syncytial virus, influenza virus, parainfluenza viruses, and adenoviruses. Compared with conventional diagnostic tests, real-time PCR increased the diagnostic yields for these viruses from 24% to 43% and from 3.5% to 36% for children and adults, respectively.

Infectious Diseases Division, International Centre for Diarrheal Disease Research, Bangladesh (icddr,b), Dhaka, Bangladesh.
Background: During the 2023-dengue outbreak in Bangladesh, a diagnostic evaluation study was conducted to investigate concurrent Zika virus (ZIKV) and dengue virus (DENV) transmission in Dhaka in 2023.
Aims: The study explored to simultaneously detect the presence of ZIKV, DENV, and/or CHIKV while considering relevant clinical and epidemiological risk factors, using a real-time multiplex RT-PCR system. Following this, it was planned to sequence the selected samples to identify genetic variations of the ZIKV infections within the population.
Identification of cuproptosis and ferroptosis-related subtypes and development of a prognostic signature in colon cancer.

Colon cancer, as a highly prevalent malignant tumor globally, poses a significant threat to human health. In recent years, ferroptosis and cuproptosis, as two novel forms of cell death, have attracted widespread attention for their potential roles in the development and treatment of colon cancer. However, the investigation into the subtypes and their impact on the survival of colon cancer patients remains understudied.

Sweetpotato Stem Rot Nematode () causes the most devastating disease affecting sweetpotato production in China. The objectives of this study were: i) establish a quantification method using real-time PCR for of sweetpotato; ii) analyze the effect of density at harvest on the percentage of disease incidence in sweetpotatoes; and iii) evaluate the effect of soil physical properties on disease incidence. Populations of isolated from 28 different production areas in Henan Province exhibited identical sequences, and then real-time PCR specific primers (PRNf and PRNr) were designed.

Neuropathic pain (NP) imposes a significant burden on individuals, manifesting as nociceptive anaphylaxis, hypersensitivity, and spontaneous pain. Previous studies have shown that traumatic stress in the nervous system can lead to excessive production of hydrogen sulfide (HS) in the gut. As a toxic gas, it can damage the nervous system through the gut-brain axis.

Department of Dermatology, Nanfang Hospital, Southern Medical University, Guangzhou, People's Republic of China.
Background: Systemic lupus erythematosus is a common autoimmune disease. Studies have suggested that defective stem cells could be involved in the pathogenesis of systemic lupus erythematosus, which leads to changes in the function of immune cells. By observing the cell morphology, autophagy, and senescence of bone marrow mesenchymal stem cells (BMSCs) from lupus mice and normal controls, this study investigated the role of IL-6 in autophagy and senescence of BMSCs and explored relevant mechanisms.
