Cereals are the major contributors to global food supply, accounting for more than half of the total human calorie requirements. Sustainable availability of quality cereal grains is an important step to address the high-priority issue of food security. High concentrations of heavy metals specifically lead (Pb) in the soil negatively affect biochemical and physiological processes regulating grain quality in cereals. The dietary intake of Pb more than desirable quantity via food chain is a major concern for humans, as it can predispose individuals to chronic health issues. In plant systems, high Pb concentrations can disrupt several key metabolic processes such as electron transport chain, cellular organelles integrity, membrane stability index, PSII connectivity, mineral metabolism, oxygen-evolving complex, and enzymatic activity. Plant growth-promoting rhizobacteria (PGPR) has been recommended as an inexpensive strategy for remediating Pb-contaminated soils. A diverse group of Ascomycetes fungi, i.e., dark septate endophytes is successfully used for this purpose. A symbiotic relationship between endophytes and host cereal induces Pb tolerance by immobilizing Pb ions. Molecular and cellular modifications in plants under Pb-stressed environments are explained by transcription factor families such as bZIP, ERF, and GARP as a regulator. The role of metal tolerance protein (MTP), natural resistance-associated macrophage protein (NRAMP), and heavy metal ATPase in decreasing Pb toxicity is well known. In the present review, we provided the contemporary synthesis of existing data regarding the effects of Pb toxicity on morpho-physiological and biochemical responses of major cereal crops. We also highlighted the mechanism/s of Pb uptake and translocation in plants, critically discussed the possible management strategies and way forward to overcome the menace of Pb toxicity in cereals.

Accurate forecasting of energy demand for electric vehicles (EVs) is crucial for maintaining the stability and reliability of power systems. By predicting demand over various periods, charging station owners can ensure a continuous energy supply. Medium-term and long-term demand predictions, which extend from a few weeks to several days, help analyze charging demand across different periods based on historical trends. This study proposes a Transformer model that utilizes an LSTM-based encoder-decoder for forecasting the demand at electric vehicle charging stations (EVCS). The proposed model is compared with traditional deep learning-based LSTM and Transformer models. The research employs open datasets from ACN, including charging data from Caltech and JPL. Both datasets are used to train and test the models. Predictions are made for 30 days, 120 days, and 240 days ahead, with results compared to actual demand. Performance is evaluated using Mean Absolute Error (MAE) and Mean Squared Error (MSE). Compared to baseline models, the proposed LSTM-Transformer model for Caltech data shows a significant improvement at the 30-day horizon, lowering MAE by up to 17.27% and MSE by 19.79%. The accuracy improvement are minor but consistent in longer horizons (120 and 240 days), with an MAE and MSE improvement of up to 5.71% and 4.85%, respectively. The LSTM-Transformer model also shows better accuracy across all horizons for JPL data by reducing MAE and MSE by up to 24.91% and 23.17% at 30 days, 5.00% and 5.17% at 120 days, and 3.90% and 4.86% at 240 days. The results indicate that the Hybrid Transformer model outperforms the baseline models for both datasets in medium-term and long-term predictions. The 30, 120, and 240-day predictions demonstrate lower error rates with the proposed model when utilizing Caltech and JPL charging data for these time frames.

Postpartum depression (PPD) is prevalent among women after childbirth, but accessing mental healthcare for PPD is challenging. This study aimed to assess the treatment gap and barriers to mental healthcare access for women with PPD symptoms living in Punjab, Pakistan. A multicenter cross-sectional study was conducted in five populous cities of Punjab from January to June 2023 by administering the questionnaire to the women using stratified random sampling. A total of 3,220 women in first 6 months postpartum were screened using the Edinburgh Postnatal Depression Scale. Of them, 1,503 women scored thirteen or above, indicating potential depressive disorder. Interviews were conducted to explore help-seeking behavior and barriers to accessing mental healthcare. Descriptive statistics along with nonparametric tests ( , Kruskal-Wallis, Mann-Whitney U) were used and group differences were examined. Scatter plot matrices with fitted lines were used to explore associations between variables. Classification and regression tree methods were used to classify the importance and contribution of different variables for the intensity of PPD. Only 2% of women (  = 33) with high PPD symptoms sought mental healthcare, and merely 5% of women (  = 75) had been in contact with a health service since the onset of their symptoms. 92.80% of women with PPD symptoms did not seek any medical attention. The majority of women, 1,215 (81%), perceived the need for mental health treatment; however, 91.23% of them did not seek treatment from healthcare services. Women who recently gave birth to a female child had higher mean depression scores compared to those who gave birth to a male child. Age, education, and birth location of newborn were significantly associated (   <  0.005) with mean barrier scores, mean social support scores, mean depression scores and treatment gap. The results of classification and regression decision tree model showed that instrumental barrier scores are the most important in predicting mean PPD scores. Women with PPD symptoms encountered considerable treatment gap and barriers to access mental health care. Integration of mental health services into obstetric care as well as PPD screening in public and private hospitals of Punjab, Pakistan is critically needed to overcome the treatment gap and barriers.

Fahr’s syndrome, also known as bilateral striopallidodendate calcinosis, is a rare inherited neurodegenerative illness characterized by abnormal calcium deposition in several areas of the brain, resulting in a wide range of neuropsychological symptoms. Fahr’s syndrome, secondary to autoimmune polyendocrine syndrome type 1, which includes adrenal insufficiency and mucocutaneous candidiasis in addition to hypoparathyroidism, is exceedingly rare. No case report has been documented to date to show the co-occurrence of Fahr’s syndrome and neuromyelitis optica spectrum disorder. Here, we discuss the case of a 30-year-old man with a previous history of seizures and symptoms of ectodermal dystrophy presented with seizures, left-sided hemiparesis, dysarthria, and other characteristics indicative of severe hypocalcemia. The neuroimaging findings strongly suggested Fahr’s syndrome, with radiographic evidence of Neuromyelitis optica spectrum disorder as longitudinal extensive transverse myelitis in the cervical spinal cord, high titers of serum aquaporin-4 antibodies, and demyelinating neuropathy on nerve conduction studies. This distinct neuropsychological presentation and neuroimaging findings led to the diagnosis of Fahr’s syndrome as a result of hypoparathyroidism caused by autoimmune polyendocrine syndrome type 1 with cooccurrence of neuromyelitis optica spectrum disorder. The patient’s clinical symptoms improved considerably after he was treated based on a provisional diagnosis. The clinical importance of our case is significant for both neuropsychiatrists and endocrinologists, as autoimmune polyendocrine syndrome should be considered as the etiology of Fahr’s syndrome. This case report also aims to report this unusual association of Neuromyelitis optica spectrum disorder with Fahr’s syndrome to give the future prospective to know whether this association is incidental or there is a missing link between these two different disorders.

SARS-CoV-2 has spread throughout the world since its discovery in China, and Malaysia is no exception. WGS has been a crucial approach in studying the evolution and genetic diversity of SARS-CoV-2 in the ongoing pandemic. Despite considerable number of SARS-CoV-2 genome sequences have been submitted to GISAID and NCBI databases, there is still scarcity of data from Malaysia. This study aims to report new Malaysian lineages of the virus, responsible for the sustained spikes in COVID-19 cases during the third wave of the pandemic. Patients with nasopharyngeal and/or oropharyngeal swabs confirmed COVID-19 positive by real-time RT-PCR with C T value < 25 were chosen for WGS. The selected SARS-CoV-2 isolates were then sequenced, characterized and analyzed along with 986 sequences of the dominant lineages of D614G variants currently circulating throughout Malaysia. The prevalence of clade GH and G formed strong ground for the presence of two Malaysian lineages of AU.2 and B.1.524 that has caused sustained spikes of cases in the country. Statistical analysis on the association of gender and age group with Malaysian lineages revealed a significant association ( p <0.05). Phylogenetic analysis revealed dispersion of 41 lineages, of these, 22 lineages are still active. Mutational analysis showed presence of unique G1223C missense mutation in transmembrane domain of the spike protein. For better understanding of the SARS-CoV-2 evolution in Malaysia especially with reference to the reported lineages, large scale studies based on WGS are warranted.

Drosophila melanogaster has long been used to demonstrate the effect of inbreeding, particularly in relation to reproductive fitness and stress tolerance. In comparison, less attention has been given to exploring the influence of inbreeding on the innate behavior of D. melanogaster. In this study, multiple replicates of six different types of crosses were set in pair conformation of the laboratory-maintained wild-type D. melanogaster. This resulted in progeny with six different levels of inbreeding coefficients. Larvae and adult flies of varied inbreeding coefficients were subjected to different behavioral assays. In addition to the expected inbreeding depression in the-egg to-adult viability, noticeable aberrations were observed in the crawling and phototaxis behaviors of larvae. Negative geotactic behavior as well as positive phototactic behavior of the flies were also found to be adversely affected with increasing levels of inbreeding. Interestingly, positively phototactic inbred flies demonstrated improved learning compared to outbred flies, potentially the consequence of purging. Flies with higher levels of inbreeding exhibited a delay in the manifestation of aggression and courtship. In summary, our findings demonstrate that inbreeding influences the innate behaviors in D. melanogaster, which in turn may affect the overall biological fitness of the flies.

Objective To find out the frequency of hyperhomocysteinemia in young ischaemic stroke patients and its relationship with early morbidity and mortality. Methods This prospective study was conducted on young ischemic stroke patients in Pakistan Atomic Energy Commission General Hospital, Islamabad. Ischaemic stroke patients of age < 45 years were selected from both the outpatient and inpatient departments. A fasting venous blood sample was sent for analysis. Data was collected through a structured proforma and were analyzed using SPSS 24.0 (IBM Corp, Armonk, NY, US). The outcome was measured at discharge using the modified Rankin scale. Results The mean age of the 71 patients in the study was 35.8 years. Overall, 36 (50.7%) cases had hyper-homocysteinemia. The frequency was significantly higher in males and in the age group 36-45 years (63.4%). Levels of homocysteine did not significantly affect the outcome at discharge. Conclusion Hyperhomocysteinaemia, a modifiable risk factor for ischaemic stroke, was seen in about half of young stroke patients. The levels of homocysteine did not correlate with early stroke outcome.

Chronic myeloid leukemia (CML) is a myeloproliferative disorder that commonly manifests in chronic, accelerated, or blast phase. Typically observed in individuals aged 60–65 years, CML is infrequently diagnosed in adolescents. The usual presentation in late adulthood involves nonspecific symptoms such as fever, fatigue, and weight loss, with rare reports of initial neurological involvement. A 17‐year‐old male presented with bilateral vision loss and profound hearing loss, alongside a medical history marked by fever, night sweats, and weight loss. A positive tuberculosis contact raised suspicions of tuberculous meningitis, while cervical and inguinal lymphadenopathy suggested the possibility of neurosarcoidosis. Despite clinical signs pointing toward a neurological cause, elevated white blood cell (WBC) count, a bone marrow biopsy, and the identification of BCR‐ABL translocation through chromosomal analysis surprisingly revealed a diagnosis of CML in the chronic phase. This case underscores the importance of considering hematological malignancy as a differential in cases of multiple cranial neuropathies, especially if supported by systemic symptoms. Understanding the diverse presentations of CML is essential for clinicians to provide timely and appropriate interventions particularly in young patients where it could mimic other neurological disorders leading to diagnostic challenges and delay in treatment initiation.

The Parkinson’s disease-amyotrophic lateral sclerosis (ALS) complex typically manifests as levodopa-responsive parkinsonism, followed by ALS. It is extremely rare for Parkinson’s disease and ALS to coexist without other neurological disorders. Named after the scientists who first described this overlap of two neurodegenerative conditions, it is referred to as Brait-Fahn-Schwartz disease. Given its variable presentation, increasing rarity, and lack of any diagnostic test, it poses a diagnostic challenge for physicians. We present a case of a 55-year-old Pakistani male experiencing progressive quadriparesis with spastic lower limbs and flaccid upper limbs, in addition to the cardinal features of idiopathic Parkinson’s disease. Since there is currently no cure available for either Parkinson’s disease or ALS, all available treatment focuses on improving quality of life, which we achieved in our patient. This case is unique in being the first incidence of Parkinson’s disease-ALS complex in a novel geographic region such as Pakistan, where genetic testing and cost constraints limit the diagnosis of rare disorders. The coexistence of extrapyramidal symptoms and pyramidal symptoms is uncommon. In such situations, physicians may overlook one group of symptoms, potentially leading to a misdiagnosis. This case highlights the value of a thorough physical examination and electrodiagnostic studies and suggests the association between Parkinson’s disease and ALS. This case demonstrates the significance of understanding when Parkinson’s disease symptoms start to appear in patients with ALS and the need to start dopaminergic therapy in those who had Parkinson’s disease features before ALS to alleviate the suffering of an individual and enhance quality of life.

Objective: To assess the attitude of resident and consultant Prosthodontists towards clinical decision-making in complete denture prosthodontics Study Design: A cross-sectional study. Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi, from Nov 2019 to Jan 2020. Methodology: Fifty trainee and consultant prosthodontists from all over the country were included in the study. A questionnaire consisting of 10 questions aimed at assessing the approach towards clinical decision-making in complete denture prosthodontics was circulated among the study subjects using Google Forms. Data was analyzed using SPSS version 24. Results: Around 20 (40%) prosthodontists regarded patient’s personal values and preferences to be “very important” in clinical decision-making in contrast to their own values. Most of the clinicians 47 (94%) believed their patients were quite satisfied with them and around 31 (62%) prosthodontists believed that “choice of the best treatment results from negotiation between patients and clinicians after they have shared technical information as well as their values and preferences about the options”. No significant difference was observed in choice of response between males and females or between prosthodontists with varying clinical experience for any of the questions asked (p>0.05). Conclusion: Prosthodontists participating in the present study demonstrated a positive attitude towards shared decisionmaking in complete denture prosthodontics. No differences were observed between males and females in terms of attitude towards shared decision-making practices.
