Innate immune cells are important players during an infection. The frequency of monocytes, myeloid-derived suppressor cells (MDSCs), natural killer (NK), and NKT cells were assessed in blood samples of children and adolescents living with HIV (CALHIV) and HIV-uninfected (HU) children. Blood samples from 10 CALHIV (treated or not) and six HU individuals were collected for approximately one year.

Here, we obtain mid-infrared waves via intra-pulse difference-frequency generation (IPDFG) driven by 16-femtosecond near-infrared pulses, and characterise the jitter of sub-cycle fractions of these waves relative to the gate pulses using electro-optic sampling (EOS). We demonstrate sub-attosecond temporal jitter at individual zero-crossings and sub-0.

Currently, mixed methods studies on robot-assisted gait training (RAGT) in patients with rare neurological diseases are lacking. This study aimed to explore the feasibility, acceptability, goal attainment and preliminary effects of RAGT in patients with common and rare neurological diseases and understand the intervention context and process.

Article Synopsis
- This study examined pediatric respiratory infections, specifically SARS and RSV, after the emergence of SARS-CoV-2 in Brazil, comparing characteristics of affected children.
- Conducted between April 2020 and April 2021, it analyzed children under 48 months admitted to a pediatric hospital, collecting samples for viral testing and using logistic regression to identify clinical differences.
- Results showed that children with RSV were generally younger, exhibited less fever, and had more upper airway symptoms compared to those with COVID-19, indicating distinct illness manifestations between the two viruses.
Article Synopsis
- The freshwater microbiome contains various bacteria that quickly react to higher nutrient levels, showing a high level of diversity on a small scale in lake environments.
- Research conducted in Lake Zurich during a cyanobacterial bloom revealed that certain sampling methods influenced bacterial growth and richness, with lower growth in localized syringe samples compared to more homogenized mixed samples.
- The study concluded that the limited dispersal of free-living bacteria in lakes can constrain their ability to transform nutrients, indicating that cyanobacterial blooms may serve as reservoirs for diverse and potentially harmful pathogens.
