Abstract
BACKGROUND Quantitative studies have provided valuable statistical insights into Health-Related Quality of Life (HRQoL) among patients with Heart Failure (HF), yet they often lack the depth to fully capture the nuanced, subjective experiences of living with HF particularly in the specific context of Jordan. This study explores the personal narratives of HF patients to understand the full impact of HF on their daily lives, revealing HRQoL aspects that quantitative metrics often miss. This is crucial in developing regions, where the increasing prevalence of HF intersects with local healthcare practices, cultural views, and patient expectations, providing key insights for tailored interventions and better patient care. METHODS Utilizing a phenomenological qualitative design, this study conducted face-to-face semi-structured interviews with 25 HF patients to deeply explore their lived experiences. Thematic analysis was employed to identify major themes related to their perceptions of HF as a disease, its impact on various HRQoL domains, and their recommended strategies to enhance HRQoL. RESULTS The study involved 25 participants (13 males, 12 females), aged 26-88 years (mean 63), with diverse education and heart failure (HF) severities. It revealed three themes: HF perceptions, its impact on health-related quality of life (HRQoL) across physical, psychosocial, spiritual, cognitive, and economic domains, and HRQoL improvement strategies. Participants had varied HF knowledge; some lacked basic understanding. The physical impact was most significant, affecting daily life and causing symptoms like breathing difficulties, coughing, edema, and fatigue. This physical aspect influenced their psychosocial and spiritual lives, cognitive functions, and economic stability, leading to fear, frustration, worry, social isolation, spiritual and cognitive challenges, and employment problems. CONCLUSIONS The results underscores the need for holistic healthcare approaches, integrating medical, psychological, and social support. Key recommendations include integrated care models, comprehensive patient education, support networks, and policy interventions to enhance HF patient care.

Abstract
Studies of induced pluripotent stem cells (iPSCs) from schizophrenia patients and control individuals revealed that the disorder is programmed at the preneuronal stage, involves a common dysregulated mRNA transcriptome, and identified Integrative Nuclear FGFR1 Signaling a common dysregulated mechanism. We used human embryonic stem cell (hESC) and iPSC-derived cerebral organoids from four controls and three schizophrenia patients to model the first trimester of in utero brain development. The schizophrenia organoids revealed an abnormal scattering of proliferating Ki67+ neural progenitor cells (NPCs) from the ventricular zone (VZ), throughout the intermediate (IZ) and cortical (CZ) zones. TBR1 pioneer neurons and reelin, which guides cortico-petal migration, were restricted from the schizophrenia cortex. The maturing neurons were abundantly developed in the subcortical regions, but were depleted from the schizophrenia cortex. The decreased intracortical connectivity was denoted by changes in the orientation and morphology of calretinin interneurons. In schizophrenia organoids, nuclear (n)FGFR1 was abundantly expressed by developing subcortical cells, but was depleted from the neuronal committed cells (NCCs) of the CZ. Transfection of dominant negative and constitutively active nFGFR1 caused widespread disruption of the neuro-ontogenic gene networks in hESC-derived NPCs and NCCs. The fgfr1 gene was the most prominent FGFR gene expressed in NPCs and NCCs, and blocking with PD173074 reproduced both the loss of nFGFR1 and cortical neuronal maturation in hESC cerebral organoids. We report for the first time, progression of the cortical malformation in schizophrenia and link it to altered FGFR1 signaling. Targeting INFS may offer a preventive treatment of schizophrenia.

Abstract
O6-Methylguanine (O6-meG) is a major mutagenic, carcinogenic and cytotoxic DNA adduct produced by various endogenous and exogenous methylating agents. We report the results of transcription past a site-specifically modified O6-meG DNA template by bacteriophage T7 RNA polymerase and human RNA polymerase II. These data show that O6-meG partially blocks T7 RNA polymerase and human RNA polymerase II elongation. In both cases, the sequences of the truncated transcripts indicate that both polymerases stop precisely at the damaged site without nucleotide incorporation opposite the lesion, while extensive misincorporation of uracil is observed in the full-length RNA. For both polymerases, computer models suggest that bypass occurs only when O6-meG adopts an anti conformation around its glycosidic bond, with the methyl group in the proximal orientation; in contrast, blockage requires the methyl group to adopt a distal conformation. Furthermore, the selection of cytosine and uracil partners opposite O6-meG is rationalized with modeled hydrogen-bonding patterns that agree with experimentally observed O6-meG:C and O6-meG:U pairing schemes. Thus, in vitro, O6-meG contributes substantially to transcriptional mutagenesis. In addition, the partial blockage of RNA polymerase II suggests that transcription-coupled DNA repair could play an auxiliary role in the clearance of this lesion.

Abstract
Damage in transcribed DNA presents a challenge to the cell because it can partially or completely block the progression of an RNA polymerase, interfering with transcription and compromising gene expression. While blockage of RNA polymerase progression is thought to trigger the recruitment of transcription-coupled DNA repair (TCR), bypass of the lesion can also occur, either error-prone or error-free. Error-prone transcription is often referred to as transcriptional mutagenesis (TM). Elucidating why some lesions pose blocks to transcription elongation while others do not remains a challenging problem. As part of an effort to understand this, we studied transcription past a 5-guanidino-4-nitroimidazole (NI) lesion, using two structurally different RNA polymerases, human RNA polymerase II (hRNAPII) and bacteriophage T7 RNA polymerase (T7RNAP). The NI damage results from the oxidation of guanine in DNA by peroxynitrite, a well known, biologically important oxidant. It is of structural interest because it is a ring-opened and conformationally flexible guanine lesion. Our results show that NI acts as a partial block to T7RNAP while posing a major block to hRNAPII, which has a more constrained active site than T7RNAP. Lesion bypass by T7RNAP induces base misincorporations and deletions opposite the lesion (C>A>-1 deletion >G >>> U), but hRNAPII exhibits error-free transcription although lesion bypass is a rare event. We employed molecular modeling methods to explain the observed blockage or bypass accompanied by nucleotide incorporation opposite the lesion. The results of the modeling studies indicate that NI's multiple hydrogen-bonding capabilities and torsional flexibility are important determinants of its effect on transcription in both enzymes. These influence the kinetics of lesion bypass and may well play a role in TM and TCR in cells.

Abstract
The DNA lesion 1,N(2)-ethenoguanine (1,N(2)-epsilon G) is formed endogenously as a by-product of lipid peroxidation or by reaction with epoxides that result from the metabolism of the industrial pollutant vinyl chloride, a known human carcinogen. DNA replication past 1,N(2)-epsilon G and site-specific mutagenesis studies on mammalian cells have established the highly mutagenic and genotoxic properties of the damaged base. However, there is as yet no information on the processing of this lesion during transcription. Here, we report the results of transcription past a site-specifically modified 1,N(2)-epsilon G DNA template. This lesion contains an exocyclic ring obstructing the Watson-Crick hydrogen-bonding edge of guanine. Our results show that 1,N(2)-epsilon G acts as a partial block to the bacteriophage T7 RNA polymerase (RNAP), which allows nucleotide incorporation in the growing RNA with the selectivity A>G>(C=-1 deletion)>>U. In contrast, 1,N(2)-epsilon G poses an absolute block to human RNAP II elongation, and nucleotide incorporation opposite the lesion is not observed. Computer modeling studies show that the more open active site of T7 RNAP allows lesion bypass when the 1,N(2)-epsilon G adopts the syn-conformation. This orientation places the exocyclic ring in a collision-free empty pocket of the polymerase, and the observed base incorporation preferences are in agreement with hydrogen-bonding possibilities between the incoming nucleotides and the Hoogsteen edge of the lesion. On the other hand, in the more crowded active site of the human RNAP II, the modeling studies show that both syn- and anti-conformations of the 1,N(2)-epsilon G are sterically impermissible. Polymerase stalling is currently believed to trigger the transcription-coupled nucleotide excision repair machinery. Thus, our data suggest that this repair pathway is likely engaged in the clearance of the 1,N(2)-epsilon G from actively transcribed DNA.

Abstract
As substance use disorders (SUD) are common in schizophrenia patients, we tested the hypothesis that comorbid patients (SUD[+]) have more positive vs. negative symptoms than non-comorbid (SUD[-]) patients. From reports identified by literature-searching we compared Positive and Negative Syndrome Scale (PANSS) ratings in schizophrenia patients with and without SUD using meta-analytic methods. Among 9 comparisons (N=725 subjects), SUD[+] patients were more often men, and abused alcohol>cannabis>cocaine. SUD[+] patients had very significantly higher PANSS-positive, and lower PANSS-negative scores. Comorbid SUD in schizophrenia patients was associated with male sex and higher PANSS positive to lower negative scores. Cause-effect relationships remain to be clarified.

Abstract
DNA damage located within a gene's transcription unit can cause RNA polymerase to stall at the modified site, resulting in a truncated transcript, or progress past, producing full-length RNA. However, it is not immediately apparent why some lesions pose strong barriers to elongation while others do not. Studies using site-specifically damaged DNA templates have demonstrated that a wide range of lesions can impede the progress of elongating transcription complexes. The collected results of this work provide evidence for the idea that subtle structural elements can influence how an RNA polymerase behaves when it encounters a DNA adduct during elongation. These elements include: (1) the ability of the RNA polymerase active site to accommodate the damaged base; (2) the size and shape of the adduct, which includes the specific modified base; (3) the stereochemistry of the adduct; (4) the base incorporated into the growing transcript; and (5) the local DNA sequence.

Abstract
The effects of atropine and cimetropium bromide, a new antimuscarinic compound with strong spasmolytic properties, were studied on human esophageal motility. Twenty healthy subjects underwent esophageal manometry with continuous monitoring of lower esophageal sphincter pressure (LESP), and of amplitude, duration and velocity of contractions of the esophageal body. After a 30-min basal period, atropine (12 micrograms/kg) or cimetropium (5 mg) were administered as an intravenous bolus in a cross-over random manner and the recording was continued for another 60 min. Twenty minutes after injection, atropine and cimetropium decreased maximally, in a similar extent, both the amplitude of contractions of the esophageal body (-65% of the basal values) and the LESP (-30% of the basal values). The duration and propagation velocity of the esophageal contractions did not change significantly after both drugs. Sixty minutes after injection of cimetropium, the amplitude of contractions of the esophageal body and LESP returned to basal values while atropine still reduced both variables. These findings indicate that cimetropium bromide has an inhibitory effect on LESP and on the amplitude of contractions of the esophageal body similar to atropine, but its action lasts less time.
