Previous research on cadmium (Cd) focused on toxicity, neglecting hormesis and its mechanisms. In this study, pakchoi seedlings exposed to varying soil Cd concentrations (CK, 5, 10, 20, 40 mg/kg) showed an inverted U-shaped growth trend (hormesis characteristics): As Cd concentration increases, biomass exhibited hormesis character (Cd5) and then disappear (Cd40). ROS levels rose in both Cd treatments, with Cd5 being intermediate between CK and Cd40.

Crop plants are severely affected by heavy metals (HMs), leading to food scarcity and economical loss. Lead (Pb) is outsourced by use of lead-based fertilizers, batteries, mining, smelting and metal processing. It significantly reduces growth, development and yield of crops cultivated on contaminated sites.

Stress tolerance in cereal crops like Sorghum is important to address food security and land development for saline agriculture. Salinity is considered one of the most devastating abiotic stresses affecting plant growth and yield, specifically in water-scared areas of the world. Biogas residue is a good source of plant nutrients with enriched fertilizer for crop yield and productivity.

Digital dermatitis (DD) is an infectious disease of the digital skin of dairy cows that is associated with compromised animal welfare and significant economic losses. The hind feet of 16,098 dairy cows from 55 herds were examined in the milking parlor, and DD lesions identified were classified using the M-score system and swabbed for PCR testing. Swabs were also collected from hind feet with normal digital skin for comparison.

The vanadium (V) toxicity predominantly is the primary limitation in restraining pepper growth. The silicon (Si) in pepper plants induced the transcript level of the polyamines metabolism pathway genes, including the arginase (CbARG), ornithine decarboxylase (CbODC), arginine decarboxylase (CbADC), N-carbamoylputrescine amidase (CbNCA), Spermidine synthase (CbSPDS), copper binding diamine oxidase (CbCuAO) to overcome the V toxicity. The polyamines, including the Spm, Spd, and Put, induced with Si about 41.

Article Synopsis
  • Plant communities consist of species with varying functional traits and evolutionary backgrounds, leading to the expectation that functional diversity increases with phylogenetic diversity.* -
  • Contrary to this expectation, a study of over 1.7 million vegetation plots showed that functional and phylogenetic diversity are weakly and negatively correlated, suggesting they operate independently.* -
  • Phylogenetic diversity is more pronounced in forests and reflects recent climate, while functional diversity is influenced by both past and recent climate, highlighting the need to assess both types of diversity for ecosystem studies and conservation strategies.*

  • * Both spinach varieties experienced similar negative effects from Cd exposure, which included reduced growth and physiological functions, while biochemical markers like malondialdehyde and hydrogen peroxide levels increased.
  • * Foliar treatments enhanced growth and gas exchange metrics and mitigated the negative biochemical effects of Cd; Desi Palak responded best to MgO-NPs, whereas Lahori Palak thrived under the combined SNP and MgO-NP treatment, suggesting potential remedies for heavy metal stress

Objectives: Exposure of spleen tissues to ionizing radiation during radiotherapy can induce cellular stress and immune-dysfunction leading to cellular senescence.

Introduction: The process of a cancerous development is facilitated by the accumulation of senescent cells. This justifies the incorporation of anti-senescent medications during splenic irradiation (SI).

Amidst depleting water resources, rising crop water needs, changing climates, and soil fertility decline from inorganic modifications of soil, the need for sustainable agricultural solutions has been more pressing. The experimental work aimed to inspect the potential of organically activated biochar in improving soil physicochemical and nutrient status as well as improving biochemical and physiological processes, and optimizing yield-related attributes under optimal and deficit irrigation conditions. Biochar enhances soil structure, water retention, and nutrient availability, while improving plant nutrient uptake and drought resilience.

  • Black adolescents in the U.S. face issues with inadequate sleep, and this research aims to explore the reasons behind changes in their sleep patterns over time.
  • The study examines how changes in socioeconomic status (SES) over a year impact sleep quality and duration among 218 Black adolescents, utilizing actigraphy to measure sleep parameters.
  • Results indicate that increases in SES correlate with improvements in sleep quality, suggesting that understanding within-group differences is crucial for addressing sleep and health disparities in this population.

  • Chitosan (CTS) and salicylic acid (SA) are studied for their potential to improve Aconitum napellus plant resilience against chromium (Cr)-induced stress, which has not been extensively researched before.
  • The experiment showed that applying CTS and SA separately or together significantly enhanced growth, chlorophyll content, and photosynthetic capabilities of the plants exposed to Cr stress.
  • The combined treatment of CTS and SA led to the most substantial improvements in plant morphology, physiological parameters, and a decrease in harmful enzymatic antioxidants, highlighting their effectiveness in combating Cr-induced stress.

Objectives: A preference for eveningness - one's perception of being most alert later in the day - is associated with negative developmental outcomes in adolescence. Sleep onset consistency is protective against such outcomes. Toward a more nuanced understanding of relations between sleep-wake processes and adolescent development, we examined weeknight sleep onset consistency as a moderator of relations between eveningness and multiple indicators of development.

  • - The study investigates the immune response triggered by two types of vaccines—an inactivated vaccine (CATTLEWIN-5K) and a modified live vaccine (MLV, Cattle Master Gold FP)—against bovine respiratory disease (BRD) in seronegative heifers.
  • - Twenty heifers were divided into three groups: a control group (no vaccination) and two vaccinated groups receiving either the MLV or inactivated vaccine. The immune response was measured by analyzing the expression of interleukin-6 (IL-6) and interferon-gamma (INF-γ) at various days post-vaccination.
  • - Results showed that both vaccines upregulated IL-6 and INF-γ levels, with

Although research has established the immediate, detrimental impact of discrimination on sleep, how changes in experiences of discrimination may be related to changes in sleep duration over multiple years is less clear. This three-year longitudinal study investigated: (1) intercept-only and linear trajectories of sleep and everyday discrimination across three years of high school; (2) ethnic/racial differences in these trajectories; and (3) the associations between changes in sleep and changes in everyday discrimination. The sample consisted of ethnically/racially minoritized adolescents from five northeast U.
