The accumulation, elimination characteristics, and toxic effects of intertidal sediment crude oil contamination in Sinonvacula constricta.

Marine oil spills lead to intertidal sediment pollution, causing benthic bioaccumulation and toxicity. However, relatively few studies have been conducted on the effects of crude oil sediment pollution on benthos. In this study, Sinonovacula constricta was used as the research object in a sediment environment to study the accumulation and elimination effects of S.

Case report: A 51-year-old diabetic patient with primary bilateral macronodular adrenal hyperplasia and primary hyperparathyroidism.

A 51-year-old female patient with diabetes mellitus and hypertension, exhibiting poor control of blood sugar and blood pressure, was unexpectedly found to have multiple large adrenal nodules, excessive cortisol secretion, and adrenocorticotropic hormone inhibition. Cortisol levels remained unresponsive to both low-dose and high-dose dexamethasone tests, leading to a diagnosis of primary bilateral macronodular adrenal hyperplasia. Concurrently, elevated blood calcium and parathyroid hormone levels, along with 99mTc-methoxyisobutyl isonitrile (99mTc-MIBI) imaging revealing increased 99mTc-MIBI uptake in the right inferior parathyroid gland, suggest the consideration of primary hyperparathyroidism.

Association of handgrip strength with aortic stenosis among adults aged 60 years and older: evidence from the 157097 UK Biobank participants.

Objective: To examine the association of handgrip strength with aortic stenosis incidence among adults aged 60 years and older.

Methods: We conducted a cohort study using the UK Biobank data to assess the relationship between handgrip strength and incident aortic stenosis in individuals aged 60 years and older. Handgrip strength was measured using a Jamar J00105 hydraulic hand dynamometer.

Dual-objective optimization of prefabricated component logistics based on JIT strategy.

Prefabricated construction involves manufacturing components in a factory and then transporting them to a construction site for assembly, yielding resource savings and improved efficiency. However, the large size and weight of prefabricated components, along with strict delivery requirements, introduce logistical challenges, such as increased carbon emissions during transport and site congestion. This study addresses the dual-objective vehicle scheduling problem for prefabricated components.

Early neurological deterioration in acute ischemic minor stroke patients with large vessel occlusion following intravenous thrombolysis.

Objective: Early identification of risk factors associated with early neurological deterioration (END) in patients with acute minor stroke and large vessel occlusion (LVO) receiving intravenous thrombolysis (IVT) could assist in formulating treatment decisions.

Methods: Consecutive patients with acute minor stroke and LVO were extracted from a single-center prospective database spanning January 2020 to December 2023. END was defined as an increase of ≥ 4 points in the National Institutes of Health Stroke Scale (NIHSS) score from baseline, or ≥ 2 points in any single NIHSS item, within 24 hours of the IVT.
