Metabolic reprogramming is recognized as a hallmark of cancer, enabling cancer cells to acquire essential biomolecules for cell growth, often characterized by upregulated glycolysis and/or fatty acid synthesis-related genes. The transcription factor forkhead box M1 (FOXM1) has been implicated in various cancers, contributing significantly to their development, including colorectal cancer (CRC), a major global health concern. Despite FOXM1's established role in cancer, its specific involvement in the Warburg effect and fatty acid biosynthesis in CRC remains unclear. We analyzed The Cancer Genome Atlas (TCGA) Colonic Adenocarcinoma and Rectal Adenocarcinoma (COADREAD) datasets to to derive the correlation of the expression levels between and multiple genes and the survival prognosis based on expression. Using two human CRC cell lines, HT29 and HCT116, we conducted RNAi or plasmid transfection procedures, followed by a series of assays, including RNA extraction, quantitative real-time polymerase chain reaction, Western blot analysis, cell metabolic assays, and immunofluorescence analysis. Higher expression levels of FOXM1 correlated with a poorer survival prognosis, and the expression of was positively correlated with glycolysis-related genes and , lipogenesis-related genes and , and . FOXM1 appeared to modulate AKT/mTOR signaling, the expression of c-Myc, proteins related to glycolysis and fatty acid biosynthesis, as well as extracellular acidification rate in HT29 and HCT116 cells. In summary, FOXM1 plays a regulatory role in glycolysis, fatty acid biosynthesis, and cellular energy consumption, thereby influencing CRC cell growth and patient prognosis.

An outbreak of dengue fever struck Tikarapada village, Rayagada district (April 2020). Among 117 fever cases, 49 tested positive for the dengue NS1 antigen. To identify mosquito-related factors in the outbreak, a survey of 101 houses found Aedes breeding sites in 11.6% of containers. Aedes aegypti (79%) and Aedes albopictus (21%) emerged from collected pupae. The village exhibited high (house index = 24.8), (container index = 11.6), (pupal index = 32.7), and (Breteau index = 40.6) indices. The findings confirmed the presence of Aedes and ample breeding sites, suggesting their role in the outbreak. A report recommending integrated vector control measures was submitted to district and state health authorities.

Evidence on the association of chronic illnesses with depression among adolescents in the Indian community setting is limited. A simple random sample of 583 adolescents, comprising 56.6% of boys and 43.4% of girls, were interviewed on home visits. Self-reports on chronic illnesses were elicited, followed by administration of Patient Health Questionnaire-9 (PHQ-9) questionnaire to screen for depression, and for confirmation of diagnosis by age-appropriate Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI Kid), or MINI. The prevalence of chronic illnesses was 8.4% (95% confidence interval [CI]: 6.3-11.0). Of these participants, 42.8% screened positive for depression. The prevalence of depression was 10.2% (95% CI: 3.4-22.2) among adolescents with chronic illness. The prevalence of physical-mental multimorbidity was 0.8% (95% CI: 0.3-2.0). The presence of chronic illness was associated with depression identified using both PHQ-9 (adjusted odds ratio [AOR] =3.1 [95% CI: 1.7-5.8], P < 0.001) and MINI Kid/MINI (AOR = 3.2 [95% CI: 1.1-9.4], P = 0.037). Adolescents with chronic illnesses can be targeted for mental morbidity screening in a bid to improve functional outcomes.

Review
Oropharyngeal cancers (OPCs) in Asia account for 42% of the global burden and over 50% of related deaths. Human papillomavirus (HPV) is involved in over 70% of OPC cases in the Western hemisphere, but its role in the Eastern hemisphere is unclear. This study reviews OPC epidemiology, including prevalence, etiological factors (such as smokeless tobacco and HPV), and their interaction. Among the SEAR countries, India had the highest incidence of HPV-related OPCs at 38.4%, while data were unavailable for most African countries, with only a 14% incidence reported. Conversely, the American region exhibited one of the highest HPV positivity rates, reaching up to 65% in different states of the USA, while Brazil reported an incidence of up to 38%. In the European Union, the UK had the highest incidence of HPV-associated OPC, reaching up to 52%. In the Western Pacific region, New Zealand demonstrated the highest incidence at up to 78%. Smokeless tobacco consumption was higher in SEAR countries, which had a relatively lower incidence of HPV infection, suggesting a negative correlation between the two. Based on our literature search, the most common detection methods used globally are immunohistochemistry for p16 and polymerized chain reaction. OPCs are a global health concern, and proper identification and classification are vital. HPV-driven cancers have better survival rates, emphasizing the need for focused research on specific problem areas based on the burden of HPV-positive or HPV-negative cancers.

Randomized Controlled Trial
BACKGROUND
Adolescents are exposed to various psycho-physiological stressors due to rapid changes in their bodies along with increased academic pressure, peer pressure, and pressures from other sources of society. Group health education sessions in schools could have a positive outcome in not only the way they perceive stress but also tackle it efficiently.
OBJECTIVE
The objective of the study was to assess the effectiveness of group health education intervention on "perceived stress" among the high school children of Kolar.
MATERIALS AND METHODS
An open-label cluster randomized controlled trial was conducted among high school students (8th, 9th, and 10th standard) in selected English Medium Schools of Kolar Taluk. The study was conducted in three phases spanning 5 months of duration. Phase I included baseline data collection wherein "perceived stress" level was captured using the Perceived Stress Scale (PSS) 10 questionnaire. Phase II was the interventional phase in the form of group health education sessions. Phase III was end-line assessment.
RESULTS
Before the intervention, 6.2%, 92.4%, and 1.5% of the students had mild, moderate, and severe stress, respectively, in the intervention group. After the intervention in the intervention group, about 57.9% had mild stress, 42.1% had moderate stress, and none had severe stress. The difference in difference analysis (DID) showed that the mean PSS scores in the intervention group changed by -8.84 while in the control group by 0.40.
CONCLUSION
Group health education delivered was effective in reducing the perceived stress levels among high school children and it is a feasible and acceptable intervention for stress in school-going adolescent children.

In this article, we consider the influence of a periodic sequence of Gaussian pulses on a chimera state in a ring of coupled FitzHugh-Nagumo systems. We found that on the way to complete spatial synchronization, one can observe a number of variations of chimera states that are not typical for the parameter range under consideration. For example, the following modes were found: breathing chimera, chimera with intermittency in the incoherent part, traveling chimera with strong intermittency, and others. For comparison, here we also consider the impact of a harmonic influence on the same chimera, and to preserve the generality of the conclusions, we compare the regimes caused by both a purely positive harmonic influence and a positive-negative one.

The plant hormone jasmonate (JA) regulates plant growth and immunity by orchestrating a genome-wide transcriptional reprogramming. In the resting stage, JASMONATE-ZIM DOMAIN (JAZ) proteins act as main repressors to regulate the expression of JA-responsive genes in the JA signaling pathway. However, the mechanisms underlying de-repression of JA-responsive genes in response to JA treatment remain elusive. Here, we report two nuclear factor Y transcription factors NF-YB2 and NF-YB3 (thereafter YB2 and YB3) play key roles in such de-repression in Arabidopsis. YB2 and YB3 function redundantly and positively regulate plant resistance against the necrotrophic pathogen Botrytis cinerea, which are specially required for transcriptional activation of a set of JA-responsive genes following inoculation. Furthermore, YB2 and YB3 modulated their expression through direct occupancy and interaction with histone demethylase Ref6 to remove repressive histone modifications. Moreover, YB2 and YB3 physically interacted with JAZ repressors and negatively modulated their abundance, which in turn attenuated the inhibition of JAZ proteins on the transcription of JA-responsive genes, thereby activating JA response and promoting disease resistance. Overall, our study reveals the positive regulators of YB2 and YB3 in JA signaling by positively regulating transcription of JA-responsive genes and negatively modulating the abundance of JAZ proteins.

NAC transcription factors (TFs) are pivotal in plant immunity against diverse pathogens. Here, we report the functional and regulatory network of MNAC3, a novel NAC TF, in rice immunity. MNAC3, a transcriptional activator, negatively modulates rice immunity against blast and bacterial leaf blight diseases and pathogen-associated molecular pattern (PAMP)-triggered immune responses. MNAC3 binds to a CACG cis-element and activates the transcription of immune-negative target genes OsINO80, OsJAZ10, and OsJAZ11. The negative function of MNAC3 in rice immunity depends on its transcription of downstream genes such as OsINO80 and OsJAZ10. MNAC3 interacts with immunity-related OsPP2C41 (a protein phosphatase), ONAC066 (a NAC TF), and OsDjA6 (a DnaJ chaperone). ONAC066 and OsPP2C41 attenuate MNAC3 transcriptional activity, while OsDjA6 promotes it. Phosphorylation of MNAC3 at S163 is critical for its negative functions in rice immunity. OsPP2C41, which plays positive roles in rice blast resistance and chitin-triggered immune responses, dephosphorylates MNAC3, suppressing its transcriptional activity on the target genes OsINO80, OsJAZ10, and OsJAZ11 and promoting the translocation of MNAC3 from nucleus to cytoplasm. These results establish a MNAC3-centered regulatory network in which OsPP2C41 dephosphorylates MNAC3, attenuating its transcriptional activity on downstream immune-negative target genes in rice. Together, these findings deepen our understanding of molecular mechanisms in rice immunity and offer a novel strategy for genetic improvement of rice disease resistance.

Randomized Controlled Trial
INTRODUCTION
This study aims to clarify differences in mood, craving, and treatment response between reward and relief/habit individuals in a study of naltrexone, varenicline, and placebo. We hypothesized that relief/habit individuals would have a poorer mood during early abstinence and higher levels of alcohol craving than reward individuals. We hypothesized that reward individuals would demonstrate better drinking outcomes on naltrexone versus placebo.
METHODS
Data were culled from a randomized, double-blind, placebo-controlled human trial of 53 individuals (18F/16M) with alcohol use disorder randomized to varenicline (n = 19), naltrexone (n = 15), or matched placebo (n = 19). In this 6-day practice quit trial, participants attempted to abstain from drinking and completed daily diaries. Participants were classified into reward or relief/habit subgroups based on self-reported motivation for drinking. Multilinear models tested differences in mood and alcohol craving between reward and relief/habit individuals. General linear models tested differences between reward and relief/habit individuals' drinking outcomes on each medication versus placebo.
RESULTS
Relief/habit individuals showed decreases in positive mood and increases in negative mood over the quit attempt across medications, compared to reward individuals (P's < .05). Reward individuals' tension decreased on naltrexone, while relief/habit individuals' tension remained stable (F = 3.64, P = .03). Reward individuals in the placebo group had higher percent days abstinent than relief individuals in the placebo group (P < .001).
DISCUSSION
This study suggests relief/habit individuals' mood worsens during early abstinence. Our finding that reward individuals' tension decreased on naltrexone and increased on placebo may suggest a clinical response to the medication.

Observational Study
BACKGROUND
CT-to-body divergence-described as the difference between preprocedural CT scans and intraprocedural lung architecture-is a significant barrier to improving diagnostic yield during navigational bronchoscopy. A major proposed contributor to CT-to-body divergence is the development of atelectasis, which can confound visualization of peripheral lung lesions via radial probe endobronchial ultrasound (RP-EBUS). High positive end-expiratory pressure (PEEP) ventilatory strategies have been used to decrease atelectasis, allowing the lesion to re-APPEAR on intraprocedure imaging. However, standardized PEEP levels may not be appropriate for all patients due to hemodynamic and ventilatory impacts.
METHODS
We performed a multicenter, prospective observational study in which patients were imaged with RP-EBUS under general anesthesia to determine if subsegmental atelectasis would resolve as incremental increases in PEEP were applied. Resolution of atelectasis was based on the transition from a non-aerated pattern to an aerated appearance on RP-EBUS. RP-EBUS images were reviewed by 3 experienced operators to determine correlation.
RESULTS
Forty-three patients underwent RP-EBUS examination following navigational bronchoscopy. Thirty-seven patients underwent incremental PEEP application and subsequent RP-EBUS imaging. Atelectasis was determined to have resolved in 33 patients (88.2%) following increased PEEP. The intraclass correlation coefficient between reviewers was 0.76. A recruitment maneuver was performed in 7 (16.3%) patients after atelectasis persisted at maximal PEEP. Atelectasis was not identified in the examined subsegments in 6 (10.8%) patients despite zero PEEP.
CONCLUSION
RP-EBUS is an effective tool to monitor what pressure atelectasis within a lung segment has resolved with increasing levels of PEEP.
