    Abstract Ischemic disorders, including myocardial infarction, cerebral ischemia, and peripheral vascular impairment, are the main common reasons for debilitating diseases and death in Western cultures. Ischemia occurs when blood circulation is reduced in tissues. Reperfusion, although commanded to return oxygen to ischemic tissues, generates paradoxical tissue responses. The responses include generating reactive oxygen species (ROS), stimulating inflammatory responses in ischemic organs, endoplasmic reticulum stress, and the expansion of postischemic capillary no-reflow, which intensifies organ damage. Multiple pathologic processes contribute to ischemia/reperfusion; therefore, targeting different pathologic processes may yield an effective therapeutic approach. Transient Receptor Potential A1 (TRPA1) belongs to the TRP family of ion channels, detects a broad range of chemicals, and promotes the transduction of noxious stimuli, e.g., methylglyoxal, ROS, and acrolein effects are attributed to the channel's sensitivity to intracellular calcium elevation or phosphoinositol phosphate modulation. Hypoxia and ischemia are associated with oxidative stress, which activates the TRPA1 channel. This review describes the role of TRPA1 and its related mechanisms that contribute to ischemia/reperfusion. Relevant articles were searched from PubMed, Scopus, Web of Sciences, and Google Scholar electronic databases, up to the end of August 2023. Based on the evidence presented here, TRPA1 may have protective or deteriorative functions during the ischemia/reperfusion process. Its function depends on the activation level, the ischemic region, the extent of lesions, and the duration of ischemia.

    Abstract Chronic pancreatitis results in the formation of pancreatic intraepithelial neoplasia (PanIN) and poses a risk of developing pancreatic cancer. Our previous study demonstrated that Krüppel-like factor 5 (KLF5) is necessary for forming acinar-to-ductal metaplasia (ADM) in acute pancreatitis. Here, we investigated the role of KLF5 in response to chronic injury in the pancreas. Human tissues originating from chronic pancreatitis patients showed increased levels of epithelial KLF5.

    Abstract Routinely collected and linked healthcare administrative datasets could be used to monitor mortality among people with hepatitis B (HBV) and C (HCV). This study aimed to evaluate the concordance in records of liver-related mortality among people with an HBV or HCV notification, between data on hospitalization for end-stage liver disease (ESLD) and death certificates. In New South Wales, Australia, HBV and HCV notifications (1993-2017) were linked to hospital admissions (2001-2018), all-cause mortality (1993-2018) and cause-specific mortality (1993-2016) datasets. Hospitalization for ESLD was defined as a first-time hospital admission due to decompensated cirrhosis (DC) or hepatocellular carcinoma (HCC). Consistency of liver death definition of mortality following hospitalization for ESLD was compared with two death certificate-based definitions of liver deaths coded among primary and secondary cause-specific mortality data, including ESLD-related (deaths due to DC and HCC) and all-liver deaths (ESLD-related and other liver-related causes). Of 63,292 and 107,430 individuals with an HBV and HCV notification, there were 4478 (2.6%) post-ESLD hospitalization deaths, 5572 (3.3%) death certificate liver disease deaths and 2910 (1.7%) death certificate ESLD deaths. Between 2001 and 2016, among HBV post-ESLD hospitalization deaths (n = 891), 63% (562) had death certificate ESLD recorded, and 83% (741) had death certificate liver disease recorded. Between 2001 and 2016, among HCV post-ESLD hospitalization deaths (n = 3587), 58% (2082) had death certificate ESLD recorded, and 87% (3135) had death certificate liver disease recorded. At least one-third of death certificates with DC and HCC as cause of death had no mention of HBV, HCV or viral hepatitis. Our study identified limitations in estimating and tracking HBV and HCV liver disease mortality using death certificate-based data only. The optimum data for this purpose is either ESLD hospitalisations with vital status information or a combination of these with cause-specific death certificate data.

    Abstract Hepatitis B virus (HBV) care cascade characterisation is important for monitoring HBV elimination progress. This study evaluated care cascade and factors associated with HBV DNA testing and treatment in New South Wales, Australia. HBV care cascade were determined through linkage of HBV notifications (1993-2017) to Medicare and pharmaceutical benefits schemes (2010-2018). Timely HBV DNA testing was within 4 weeks of HBV notification. Multivariate Cox proportional hazards regression evaluated factors associated with HBV DNA testing and treatment. Among 15,202 people with HBV notification, 10,479 (69%) were tested for HBV DNA. A total of 3179 (21%) initiated HBV treatment. HBV DNA testing was more likely among age ≥45 years (adjusted hazard ratio [aHR] 1.07, 95% CI: 1.02, 1.12), hepatocellular carcinoma (HCC) (aHR 1.23, 95% CI: 1.01, 1.50), coinfection (aHR 1.61, 95% CI: 1.23, 2.09), later notification (2014-2017) (aHR 1.21, 95% CI: 1.16, 1.26) and less likely among females (aHR 0.95, 95% CI: 0.91, 0.99), history of alcohol use disorder (AUD) (aHR 0.77, 95% CI: 0.66, 0.89), HCV coinfection (aHR .62, 95% CI: 0.55, 0.70) and Indigenous peoples (aHR 0.84, 95% CI: 0.71, 0.98). HBV treatment was associated with age ≥45 years (aHR 1.35, 95% CI: 1.24, 1.48), decompensated cirrhosis (aHR 2.07, 95% CI: 1.62, 2.65), HCC (aHR 2.96, 95% CI: 2.35, 3.74), HIV coinfection (aHR 4.27, 95% CI: 3.43, 5.31) and later notification (2014-2017) (aHR 1.37, 95% CI: 1.26, 1.47). HBV treatment was less likely among females (aHR 0.68, 95% CI: 0.63, 0.73) and Indigenous peoples (aHR 0.58, 95% CI: 0.42, 0.80). HBV DNA testing and treatment coverage have increased, but remain sub-optimal among some key populations.

    Abstract The hepatitis C virus (HCV) care cascade characterization is important for monitoring progress towards HCV elimination. This study evaluated HCV care cascade and factors associated with treatment during pre-DAA (2011-2012 and 2013-2015) and DAA (2016-2018) eras in New South Wales (NSW), Australia. We conducted a cohort study of people with an HCV notification (1993 to 2017) through end 2018, linked to administrative datasets, including HCV treatment and non-hospital services. Those aged <18 years, died within first 6 months of study period or notification, and who had successful HCV treatment in period before were excluded. Sex-specific spontaneous viral clearance was incorporated to estimate treatment-eligible population. The study population in each period were cumulative and brought forward from one period to the next. Among 115,667 people with HCV notification, 87,063 fulfilled eligibility criteria. During 2011 to 2012, 2013 to 2015, and 2016 to 2018, cumulative HCV notifications were 71,677, 77,969, and 80,017; 52,016, 56,793, and 57,467 were eligible for treatment; 29%, 48%, and 64% confirmed HCV RNA positive; and 0.6%, 5%, and 38% initiated HCV treatment, respectively. Birth cohort 1945 to 1964 (vs. ≥1965), males, non-Aboriginal ethnicity, regional/rural area of residence, and HCV/HIV co-infection were associated with higher treatment uptake. Incarceration and drug dependence were associated with higher treatment uptake during the DAA era. In Australia, many marginalized populations including those incarcerated and those with drug dependence have equitable treatment uptake in the DAA era. Targeted strategies are required to enhance treatment uptake for females and Aboriginal populations.

    Abstract This study presents a fractional-order adaptive high-gain controller for control of depth of anaesthesia. To determine the depth of anaesthesia, the bispectral index (BIS) is utilised. To attain the desired BIS, the propofol infusion rate (as the control signal) should be appropriately adjusted. The effect of the propofol on the human body is modelled with the pharmacokinetic-pharmacodynamic (PK/PD) model. Physical properties of the patient such as gender, age, height and a like determine the parameters of the PK/PD model. This necessitates us to employ an appropriate adaptive controller. To attain this goal, a fractional-order adaptive high-gain controller is constructed to solve the tracking problem for minimum phase systems with relative degree two (such as the PK/PD model). This leads to a time-varying gain adjusting according to a fractional-order adaptation mechanism. Simulation results performed on various patients (considering the external disturbance and the measurement noise) show the effectiveness of the proposed method.

    Abstract Alnustone (4(E)-,6(E)-1,7-Diphenyl-hepta-4,6-dien-3-one) is a non-phenolic natural diarylheptanoid, which was first isolated and identified from the male flower of Alnus pendula (Betulaceae). It can also be isolated from Curcuma xanthorrhiza Roxb (Zingiberaceae) rhizomes and Alpinia katsumadai Hayata (Zingiberaceae) seeds. It was first synthesized through a five-step process from β-phenyl propionyl chloride. In later years, new methods for synthesizing Alnustone were designed and performed with different yields. Due to the various therapeutic effects exhibited by alnustone like other diarylheptanoids, its biological activities such as antioxidant, antibacterial, and anti-inflammatory properties have been the subject of many studies. This article has reviewed different aspects of this valuable natural compound, including its natural and synthetic sources, therapeutic effects, and pharmacokinetics as a potential future therapeutic agent.

    Abstract Small RNA (sRNA)-mediated RNA interference (RNAi) is a conserved eukaryotic cellular process associated with immune defense and pathogen virulence. The cross-kingdom transfer of noncoding regulatory sRNAs between host and pathogen can be mediated via lipid, membrane-bound extracellular vesicles (EVs). Several studies have reported in mammalian and plant systems there is selective packaging of sRNAs into EVs. In mammals, sequence patterns and structural motifs are implicated in signaling pathways related to EV cargo sorting. However, in the emerging plant EV field, there is a lack of knowledge of the mechanisms involved in selecting sRNAs for EV transport. In this study, we accessed publicly available databases where the sRNA content of plant EVs has been characterized from control plants and those released in response to fungal pathogen infection. An in-depth analysis revealed 158 sRNAs are EV packaged, with ∼60 % sharing a sequence motif and 98.1 % forming a secondary hairpin stem-loop structure. Many of the predicted plant targets for the EV sRNAs were associated with biological pathways involved in metabolism and regulation processes. Overall, our in silico analysis of sRNAs packaged in plant EVs highlight that a computational approach can offer valuable insights into the cross-kingdom EV transport of sRNAs.

    Abstract The present study aimed to assess the impact of transcranial direct current stimulation (tDCS) on different domains of inhibitory control in children with mild or severe ADHD symptoms. Twenty-four children with ADHD, in two groups with severe and mild symptoms, received anodal or sham tDCS over the right dorsolateral prefrontal cortex (dlPFC) during performing inhibitory control tasks. A significant main effect of stimulation condition was found that was limited to the circle tracing task, and the incongruent condition of the flanker task. Moreover, the main effects of stimulation condition and group were non-significant, but their interaction was significant for No-Go accuracy. The results suggest that the right dlPFC has a crucial role in ongoing inhibition in children with ADHD, and that tDCS has a partially symptom severity-dependent effect on inhibitory control. These findings are discussed in connection with severity-dependent psychopathology.

    Abstract This study aimed to identify the factors associated with timely (within four weeks) HCV RNA testing and timely (within six months) DAA initiation following HCV notification in the DAA era. We conducted a cohort study of people with an HCV notification in NSW, Australia. Notifications of positive HCV serology were linked to administrative datasets. Weights were applied to account for spontaneous clearance. Logistic regression analyses were performed. Among 5582 people with an HCV notification during 2016–2017, 3867 (69%) were tested for HCV RNA, including 2770 (50%) who received timely testing. Among an estimated 3925 people with chronic HCV infection, 2372 (60%) initiated DAA therapy, including 1370 (35%) who received timely treatment. Factors associated with timely HCV RNA testing included age (≥30 years), female sex, non-Aboriginal ethnicity, country of birth being Australia, and no history of drug dependence. Factors associated with timely treatment were age (≥30 years), male sex, non-Aboriginal ethnicity, country of birth being Australia, no history of drug dependence, and HCV/HIV co-infection. In the DAA era, 50% of people with an HCV notification did not receive timely HCV RNA testing. Most people with an HCV infection received therapy; however, DAA initiation was delayed among many.
