A total of 21 different wines (13 reds, 5 whites, and 3 rosés) were kept at 25 °C in anoxia for 379 days. Free and total forms of H2S and methanethiol (MeSH) and dimethylsulfide (DMS) were measured initially and after 117, 221, and 379 days of storage. Levels of free H2S, free and total MeSH, and DMS continuously increased during storage, while levels of total H2S remained essentially unchanged. Average increases of free H2S amount to 6.2 μg/L (from 1.1 to 12.9 μg/L), those of free MeSH to 1.6 μg/L (from 0.7 to 3.5 μg/L), and those of total MeSH to 1.9 μg/L (from 1.1 to 3.0 μg/L), whereas those of DMS were 27.8 μg/L (from 11 to 69 μg/L). The fraction of H2S under free forms significantly increased, suggesting that release is a major factor explaining H2S increases. All increases can be satisfactorily predicted from data obtained at 50 °C.

Background: Goal-directed haemodynamic therapy (GDHT) aims to optimize haemodynamic variables. However, its effectiveness in reducing postoperative complications in major abdominal surgery, particularly when targeting both arterial pressure and flow variables, remains unclear. This meta-analysis addresses this by evaluating GDHT using uncalibrated pulse contour (uPC) methods.

Cancer immunotherapies with antibodies blocking immune checkpoint molecules are clinically active across multiple cancer entities and have markedly improved cancer treatment. Yet, response rates are still limited, and tumour progression commonly occurs. Soluble and cell-bound factors in the tumour microenvironment negatively affect cancer immunity.

Article Synopsis
- Microsatellites, or simple sequence repeats (SSRs), are important genetic markers in plants, but a thorough identification in the Argania spinosa L. genome has not been done until now.
- This study identified 5351 SSRs from 66,280 coding sequences (CDSs) in A. spinosa, with tri-nucleotide motifs being the most common.
- An online database (AsSSRdb) was created to share these SSRs, providing resources for DNA fingerprinting and genetic studies in argan and similar species.

Background And Objectives: Anti-NMDA receptor (anti-NMDAR) encephalitis generally manifests in young adults. Although 80%-90% returns to independence, the majority experience persistent cognitive and psychosocial difficulties. Studies have demonstrated that cognitive recovery may continue for years; the temporal trajectory is largely unknown, as are factors influencing cognitive/psychosocial recovery.

Article Synopsis
- - Kalm ex L. is an evergreen shrub valuable for its methyl salicylate content and ornamental and medicinal properties, but lacks comprehensive genomic data, prompting this study.
- - Researchers conducted high-throughput sequencing to assemble the genome, obtaining 417 Mb of data with high quality (47.94 Gb) and identifying over 26,000 protein-coding genes and numerous SSRs (simple sequence repeats).
- - The study also identified thousands of transcription factors, transcription regulators, and protein kinases, while performing phylogenetic analyses to gain insights into the genetic relationships among species.
