Chronic myeloid leukemia (CML) is a myeloproliferative disorder that commonly manifests in chronic, accelerated, or blast phase. Typically observed in individuals aged 60-65 years, CML is infrequently diagnosed in adolescents. The usual presentation in late adulthood involves nonspecific symptoms such as fever, fatigue, and weight loss, with rare reports of initial neurological involvement.

The main stream of the Tarim River is a crucial part of China's ecological security strategy within the "two screens and three belts" framework, serving the "northern sand control belt" and the ecological civilization corridor. Evaluating and understanding desertification dynamics and driving factors is essential for achieving the United Nations Sustainable Development Goals and promoting ecological civilization. This study, based on the United Nations Convention to Combat Desertification, quantified the desertification process of the Tarim River's main stream from 1990 to 2020 using Landsat series satellite imagery from Google Earth Engine.

  • Neurosarcoidosis is a rare form of sarcoidosis that affects the nervous system, leading to symptoms like seizures, cognitive issues, and cranial nerve problems, which complicate diagnosis and management due to their variability.
  • Diagnosing the condition requires a mix of clinical assessments, advanced imaging (like high-resolution MRI and PET scans), and lab tests, but it can be mistaken for conditions like multiple sclerosis.
  • Treatment often starts with corticosteroids and may include immunosuppressants or biologic therapies for more severe cases, with ongoing research aimed at better understanding the disease and improving therapies through biomarkers and innovative technologies.

  • Pregnancy luteoma (PL) is a rare ovarian lesion that can be mistaken for cancer, making it tough to diagnose.
  • It often appears as asymptomatic masses in the ovaries during pregnancy, influenced by hormonal changes like increased hCG.
  • A case of a 23-year-old pregnant woman with abdominal pain led to surgery, where PL was confirmed after further testing, despite initial concerns of malignancy.

The effects of engineered steam exploded biochar on the phytoavailability of toxic elements in the shared- and nonshared-rhizosphere of vegetable-grass intercropping system have not been investigated yet. Therefore, we explored and elucidated the synergistic effect of pristine rape-straw biochar (BC), steam exploded BC (BCSE), KMnO-modified BCSE (BCSEMn), and hydroxyapatite-modified BCSE (BCSEHA) on the solubility, fractionation and phytoavailability of lead (Pb) in a vegetable-grass intercropping system. In a rhizosphere box, Brassica chinensis L.

Hirschsprung disease (HD) is a congenital disorder characterized by the absence of ganglion cells in the distal colon and rectum, leading to functional obstruction and severe constipation. Over the past decades, the surgical management of HD has significantly evolved, with minimally invasive surgery (MIS) techniques revolutionizing treatment approaches. This review explores recent innovations in MIS for HD, focusing on laparoscopic, transanal endorectal pull-through (TERPT), and robotic-assisted techniques.

Objectives: In Sindh Province, Pakistan, confirmed Crimean-Congo haemorrhagic fever (CCHF) increased from zero in 2008 to 16 in 2015-2016. To counter this increase, in 2016, we initiated structured CCHF surveillance to improve estimates of risk factors for CCHF in Sindh and to identify potential interventions.

Methods: Beginning in 2016, all referral hospitals in Sindh reported all CCHF cases to surveillance agents.

Genome-wide association studies (GWAS) have been instrumental in elucidating the genetic architecture of various traits and diseases. Despite the success of GWAS, inherent limitations such as identifying rare and ultra-rare variants, the potential for spurious associations, and in pinpointing causative agents can undermine diagnostic capabilities. This review provides an overview of GWAS and highlights recent advances in genetics that employ a range of methodologies, including Whole Genome Sequencing (WGS), Mendelian Randomization (MR), the Pangenome's high-quality T2T-CHM13 panel, and the Human BioMolecular Atlas Program (HuBMAP), as potential enablers of current and future GWAS research.

The Northern Eurasia Earth Science Partnership Initiative (NEESPI) was established to address the large-scale environmental change across this region. Regardless of the increasingly insightful literature addressing vegetation change across Central Asia, the biogeophysical warming effects of vegetation shifts still need to be clarified. To contribute, the utility of robust satellite observation is explored to evaluate the surface warming effects of vegetation shifts across Central Asia, which is among NEEPSI's hotspots.
