RESUMO
Parsley (Petroselinum crispum) is herb with many biological and medicinal benefits for humans. However, growth on zinc (Zn) and cadmium (Cd) contaminated sites might get severely affected due to over accumulation of heavy metals (HM) in different plant tissues. Antioxidants play a crucial role in minimizing the negative effects of HM. The present study investigates the effects of Zn and Cd stress on P. crispum morphological parameters, enzymatic/non-enzymatic antioxidant profiling and metal accumulation in shoot/root. Plants were exposed to different concentrations of Zn (50, 100, 150 and 200 µM) and Cd (10, 20, 40 and 80 µM) along with control (no stress), in soil-less Hoagland's solution. The results showed that Zn and Cd substantially decrease the growth parameters with increased contents of malondialdehyde (MDA), hydrogen peroxide (H2O2), and electrolyte leakage (EL). Non-enzymatic antioxidant activities, like total phenolic contents (TPC) and ferric reducing antioxidant power (FRAP), were induced high in leaves only upon Cd stress and contrarily decreased upon Zn stress. Total flavonoid contents (TFC) were decreased under Zn and Cd stress. Enzymatic antioxidant activities like superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) were also strongly induced upon Cd stress. At the same time, SOD and guaiacol peroxidase (GPX) activity was induced significantly upon Zn stress. Cd uptake and accumulation was notably high in roots as compared to shoots, which suggests P. crispum have a reduced ability to translocate Cd towards aboveground parts (leaves). Additionally, strong induction of antioxidants by P. crispum under Cd stress might indicate the capacity to effectively re-modulate its physiological response. However, further investigations regarding other HMs and experiments at the molecular level are still needed.

In the dynamic landscape of Breast Cancer (BC), Oligo- Metastatic Breast Cancer (OMBC) presents unique challenges and opportunities. This comprehensive review delves into current strategies for addressing OMBC, covering locoregional and site-specific metastasis management, and addressing both surgical and minimally invasive therapies as essential components. Moreover, the transformative role of Artificial Intelligence (AI) is spotlighted. However, while the future looks promising, several limitations need addressing, including the need for further research, especially in diverse patient populations and resource-challenged settings. AI implementation may require overcoming the lack of Electronic Health Records acceptance in resource-challenged countries, which contributes to a scarcity of large datasets for AI training. As AI continues to evolve, validation and regulatory aspects must be continually addressed for seamless integration into clinical practice. In summary, this review outlines the evolving landscape of OMBC management, emphasizing the need for comprehensive research, global collaboration, and innovative AI solutions to enhance patient care and outcomes.

Background Pakistan's hereditary breast cancer has a higher-than-average prevalence. Our acceptability of prophylactic risk-reducing mastectomy (PRRM) still needs to be determined, and genetic testing still needs to be offered to all eligible. The aim is to determine the number of women presenting to our centre who availed of PRRM after positive genetic tests and the main reasons restraining them from considering PRRM.Materials and methods This study is a single-centre, prospective cohort. We collected data from 2017 to 2022 on BRCA1/2 and other (P/LP) gene-positive patients. Continuous variables are presented as means (±SD) and categorical variables in percentages, with a significant P-value of ≤ 0.05.Results Out of 477 tested individuals, only 95(20.12%) had a positive result. BRCA1/2 was positive in 70 cases, while P/LP variants were in 24 cases. Only 32.6% of eligible families underwent genetic testing, with 54.8% positivity. Altogether, 92.6% of patients had BRCA1/2-related cancers. Only 25/95(26.3%) individuals availed of PRRM, the majority had contralateral risk-reducing mastectomy 68% with a 20% reconstruction rate. The main reasons to decline PRRM were false belief of not having any disease 57.44%, followed by family/spouse pressure 51%, body appearance/societal perception, fear of complications/quality of life and financial constraints.Conclusion Genetic testing and its implications are still a grey area for LMICs, primarily due to the scarcity of centres offering genetic testing to eligible populations, followed by prevalent perceptions about prophylactic surgeries among the masses. Addressing relevant issues in LMICs is the need of time.

Breast Cancer Stem Cells (BCSCs), unlike normal breast cells, exhibit the potential for self-regeneration and tumour formation and express unique markers. Studies have highlighted their role in tumour progression, recurrence, and treatment resistance. BCSCs can be one of the reasons that resistance is encountered despite recent advances in the treatment of breast cancer (BC). This review underlines the clinical implications at the molecular level of different cellular pathways, cellular level interactions in Tumour Micro Environment (TME), and types of markers and receptors involved in tumorigenesis. It accentuates the importance of comprehensive targeted treatment options available for BCSCs so that targeted modalities can be introduced to deal with treatment resistance. Stem cells (SCs) are a developing field, and limited data is available from our country to use stem cell-targeted treatment plans as a therapeutic option. Therefore, this literature review will provide insight for future research in this domain.

Meckel's diverticulum (MD)1, the most common congenital anomaly of the gastrointestinal tract, occurs in 2% of the population with males being more symptomatic than females. In this case, a 32-year-old male presented with sudden onset colicky abdominal pain, bilious vomiting, and absolute constipation. Emergency laparotomy was done on his virgin abdomen, as a result MD and vitelline cyst along with a fibrous cord connecting the two were identified. Knotting of an ileal loop around this cord had resulted in intestinal obstruction. Meckel's diverticulectomy, along with cord resection, was carried out. The patient made smooth recovery and was discharged on the fifth postoperative day with no complications. The importance of this study is to highlight the case of symptomatic MD in an adult male as it can be a cause of intestinal obstruction and should always be considered in a patient presenting with symptoms of intestinal obstruction.

Metabolic disorders often lead to cardiac complications. Metabolic deregulations during diabetic conditions are linked to mitochondrial dysfunctions, which are the key contributing factors in cardiac hypertrophy. However, the underlying mechanisms involved in diabetes-induced cardiac hypertrophy are poorly understood. In the current study, we initially established a diabetic rat model by alloxan-administration, which was validated by peripheral glucose measurement. Diabetic rats displayed myocardial stiffness and fibrosis, changes in heart weight/body weight, heart weight/tibia length ratios, and enhanced size of myocytes, which altogether demonstrated the establishment of diabetic cardiac hypertrophy (DCH). Furthermore, we examined the expression of genes associated with mitochondrial signaling impairment. Our data show that the expression of PGC-1α, cytochrome c, MFN-2, and Drp-1 was deregulated. Mitochondrial-signaling impairment was further validated by redox-system dysregulation, which showed a significant increase in ROS and thiobarbituric acid reactive substances, both in serum and heart tissue, whereas the superoxide dismutase, catalase, and glutathione levels were decreased. Additionally, the expression levels of pro-apoptotic gene PUMA and stress marker GATA-4 genes were elevated, whereas ARC, PPARα, and Bcl-2 expression levels were decreased in the heart tissues of diabetic rats. Importantly, these alloxan-induced impairments were rescued by N-acetyl cysteine, ascorbic acid, and selenium treatment. This was demonstrated by the amelioration of myocardial stiffness, fibrosis, mitochondrial gene expression, lipid profile, restoration of myocyte size, reduced oxidative stress, and the activation of enzymes associated with antioxidant activities. Altogether, these data indicate that the improvement of mitochondrial dysfunction by protective agents such as N-acetyl cysteine, selenium, and ascorbic acid could rescue diabetes-associated cardiac complications, including DCH.

Diabetic kidney disease is one of the most common microvascular complications of diabetes mellitus with consequences of diabetic nephropathy. Here we amined to evaluate the nephroprotective potential of methanolic Mentha longifolia (MML) against serotonin-induced hypoglycemia allied toxicity in the rat model of diabetes. Diabetes was induced in rats via alloxan administration and validated by blood glucose level measurement. After that, the animals were treated with serotonin and methanolic extract of Mentha longifolia. Surprisingly, serotonin treatment significantly reduced the glucose levels to hypoglycemic conditions, accompanied by impaired redox defense system, abnormal kidney histopathology, dyslipidemia, and altered level of liver toxicity markers. Interestingly these changes were rescued by the methanolic extract of M. longifolia. The present study suggests that impaired serotonin levels during diabetic conditions may accelerate hypoglycemic allied free radical-dependent abnormalities; however, medicinal plants like M. longifolia can reduce these deleterious effects by scavenging free radicals and their associated toxicity.

Exposure to environmental toxicants such as Bisphenol A (BPA) has raised serious health issues globally particularly in developing countries. It is ubiquitously used in the manufacturing of canned food and feeding bottles. BPA generated reactive oxygen species can lead to several diseases including cardiotoxicity. However, the endpoints stimulated in BPA cardiotoxicity yet need to be investigated. The current study was aimed to investigate the underlying molecular pathways which may contribute in revealing the protective effects of Pistacia integerrima against BPA induced oxidative stress. The dose of 100 µg/kg BW of BPA, 200 mg/kg BW P. integerrima, and 4 mg/kg BW melatonin was administered to Sprague Dawley rats. Present results of western blotting and qRT-PCR showed the increased expression of p53, PUMA and Drp1, while downregulation of Ubc13 in heart tissues of BPA treated group whereas the levels were reversed upon treatment with P. integerrima. The role of BPA in heart tissue apoptosis was further confirmed by the increased level of P-p53, cytochrome C and disrupted cellular architecture whereas the P. integerrima has shown its ameliorative potential by mitigating the adverse effects of BPA. Moreover, the oxidant, antioxidant, lipid, and liver markers profile has also revealed the therapeutic potential of P. integerrima by maintaining the levels in the normal range. However, melatonin has also manifested the normalized expression of apoptotic markers, biochemical markers, and tissue architecture. Conclusively, the data suggest that P. integerrima may be a potential candidate for the treatment of BPA induced toxicity by neutralizing the oxidative stress through Ubc13/p53 pathway.

PURPOSE: Facial fractures are a harbinger when it comes to airway management. Facial fractures can cause airway obstruction or preclude the use of intubation. We aim to examine the etiologies, types of facial fractures, and the risk factors that may lead to requirement of an advance airway. METHODS: A retrospective chart review was performed of all facial fractures in the adult population in a level 1 trauma center in an urban environment (University Hospital in Newark, NJ). Patient demographics were collected, as well as location of fractures, concomitant injuries, and course of hospital stay. RESULTS: During the period examined, 2626 patients were identified as 18 years or older and with facial fracture. Among these patients, 443 received airway management. Mean age was 34.21 years (range, 18-95 years), with a male predominance of 91.9%. One hundred nineteen patients were intubated on, or before, arrival to the trauma bay. One hundred three patients required surgical airways on arrival to the trauma bay, and 91 of these patients were also reported to have been intubated before arrival. There were a total of 741 fractures identified on radiologic imaging. The most common fractures observed were orbital fractures, frontal sinus fractures, and nasal fractures. Mean Glasgow Coma Scale score on arrival was 9.45 (range, 3-15). Gunshot wound was also the most common etiology among those who were intubated and those who received a surgical airway. The most common concomitant injuries were traumatic brain injury, intracranial hemorrhage, and skull fracture. Forty-one patients died, most of which were intubated during their hospital course. CONCLUSIONS: There is a dearth of literature detailing standardization of airway management for patients who present with facial fractures. The difference between intubation and surgical airway is often a subjective judgment call, but the authors believe that a more streamlined process can be elucidated after analyzing previous trends as well as variabilities in patient survival and prognosis.

BACKGROUND: Nocturnal enuresis (NE) is a common symptom in children worldwide. International Children's Continence Society (ICCS) defines enuresis as either mono-symptomatic, NE with lower urinary tract symptoms and NE with co-morbid conditions. The objectives of this study were to determine the frequencies and types of NE and associated symptoms and conditions in children aged 5 to 16 years based on ICCS criteria. METHODS: A multi-center cross sectional study was conducted between November 2012 and December 2013 in the primary care clinics of four hospitals in Karachi. Children aged five to fifteen years were included through consecutive sampling. Informed consent was obtained from the parents and a pre-coded semi-structured questionnaire was used to obtain the information. Data was entered on SPSS version 20.0 and multivariable logistic regression analysis was used for data analysis. RESULTS: Out of 429 children aged between five and sixteen years, 243(56.9%) were boys and the remaining 186(43.1%) were girls. One hundred and eighty three children (43%) had nocturnal enuresis (NE). Forty four (10.3%), had mono-symptomatic NE, 57(31.1%) had associated lower urinary tract symptoms (NE-LUTS), whereas 30 (16.3%) had NE with a co-morbid condition. Fifty two (28.4%) NE's had at least one of both LUTS and a co-morbid condition. Out of the 246(57%) non-enuretic's, 31(12.6%) had a LUTS, 95(38.6%) had a co-morbid condition and 57(23.2%) had at least one of both LUTS and a co-morbid condition. The remaining 63 (25.6%) were symptom free. Increased voiding frequency, urgency, dysuria, suprapubic pain and daytime incontinence were the LUTS significantly associated with NE. Co-morbid conditions significantly associated with NE included constipation, congenital defects, developmental delay, and learning and sleep problems. CONCLUSION: Although NE can be an only symptom, it is often associated with lower urinary tract symptoms like dysuria, urgency, suprapubic pain, and daytime incontinence. Children presenting with NE often have co-morbid conditions like constipation, urinary tract infection, sleep disorders, and developmental delay. Many children presenting with these conditions as the primary complaint may also have NE. It should be addressed as unrecognized and untreated NE can cause additional morbidity and distress.

BACKGROUND: Patients who had one caesarean section were previously not given a trial of scar due to fear of increased morbidity. However, recently there has been a trend to give a trial of labour to patients with a previous caesarean section for a non-recurrent cause. Medical evidence indicates that 60-80% of women can achieve vaginal delivery after a previous lower segment caesarean section. Proper selection of patients for trial of scar and vigilant monitoring during labour will achieve successful maternal and perinatal outcome. The objective of our study is to establish the fact that vaginal delivery after one caesarean section has a high success rate in patients with previous one caesarean section for non-recurrent cause. METHODS: The study was conducted in Ayub Teaching Abbottabad, Gynae-B Unit. All labouring patients, during the study period of five years, with previous one caesarean section and between 37 weeks to 41 weeks of gestation for a non-recurrent cause were included in the study. Data was recorded on special pro forma designed for the purpose. Patients who had previous classical caesarean section, more than one caesarean section, and previous caesarean section with severe wound infection, transverse lie and placenta previa in present pregnancy were excluded. Foetal macrosomia (wt>4 kg) and severe IUGR with compromised blood flow on Doppler in present pregnancy were also not considered suitable for the study. Patients who had any absolute contraindication for vaginal delivery were also excluded. RESULTS: There were 12505 deliveries during the study period. Total vaginal deliveries were 8790 and total caesarean sections were 3715. Caesarean section rate was 29.7%. Out of these 8790 patients, 764 patients were given a trial of scar and 535 patients delivered successfully vaginally (70%). Women who presented with spontaneous onset of labour were more likely to deliver vaginally (74.8%) as compared to induction group (27.1%). CONCLUSIONS: Trial of vaginal birth after caesarean (VBAC) in selected cases has great importance in the present era of the rising rate of primary caesarean section.

BACKGROUND: Traumatic subdural hematoma is one of the lethal injuries to brain. Various surgical techniques are used to evacuate the acute subdural hematoma. The hematoma evacuation can either be done by opening of dura by multiple slits or by opening of dura in single large c shape and then doing the expansile duraplasty. Present study aimed to compare both these techniques. METHODS: This randomized control study was conducted in department of neurosurgery, Ayub Medical College, Abbottabad from July 2011 to July 2013. A total of 59 patients were included in this study, which were randomly allocated in two groups (i.e., group A and group B) for decompressive craniectomy. Thirty-one patients were operated by craniectomy with full dural flap opening (Group A), and 28 patients were operated by craniectomy with multidural-slits (Group B). Glasgow Outcome score (GOS) at 6 weeks after the surgery was used to determine the outcome. RESULTS: Mean age of the patients was 33.4±12.8 years. Majority were males. In group A 51.6 % (16) of the patients survived out of which a favourable outcome (GOC 3-5) was observed in 41.9% of the patients, and 9.1% of patients ended up in vegetative state. While in group B 46.4% (13) of the patients survived among which favourable outcome was seen in 39.3% of patients and 7.1% of patients ended up in vegetative state. The difference in outcome measure is insignificant. CONCLUSIONS: There was no statistically significant difference among the two groups as regards the mortality, GOS, frequency of complications and hospital. While the duration of surgery was significantly shorter in patients operated with dural slits.

The control of infections is one of the key strategies to treat cuts, wounds, lung, and skin infections. In this study the folkloric use of Rumex dentatus (R. dentatus) roots in the mentioned conditions was scientifically investigated. The methanolic (MeOH) crude extract of R. dentatus root was fractionated (n-hexane, ethyl acetate and water) via bioassay-guided method, and its antibacterial activity was evaluated using the agar well diffusion and Minimum inhibitory concentration (MIC) assays against clinical isolate of Pseudomonas aeruginosa (P. aeruginosa). The antibiofilm activity was measured using the crystal violet staining method. The crude extract, fractions and sub-fractions tested showed the MICs values ranging from 200 to 1000 µg/mL respectively. Among the fractions, notably, the water fraction exhibited the highest activity against P. aeruginosa. The water fraction was then subjected to thin layer chromatography (TLC). Following spectrometric analysis using HPLC-ESI-Q-TOF-MS, gallic acid and emodin were identified as the primary components within the same fraction, responsible for eliciting antibacterial and antibiofilm effects. The in-silico studies conducted with AutoDock Vina on the LasR protein, using both isolated gallic acid and emodin, confirm the binding affinity of these molecules to the active sites of the LasR protein that has regulatory role in building of biofilm formation and its pathogenicity. By scientifically validating the infection-controlling properties of R. dentatus, this research provides compelling evidence that supports its traditional use as reported in folklore. Moreover, this study contributes to our understanding of the plant's potential in managing infections, thereby substantiating its traditional therapeutic application in a scientific context.
RESUMO
Having just one root canal in a primary mandibular first molar is an extremely unusual congenital defect. One possible cause of this odd root shape is the invagination of Hertwig's epithelial root sheath (HERS) failing. A pediatric dentist may successfully provide root canal therapy by drawing on extensive knowledge of root canal evaluation, morphological and anatomical differences of primary teeth, and other relevant topics. Herein, we detail the treatment of a singular root, single canal primary mandibular first molar that presented with a unique morphology. The patient underwent pulpectomy, obturation, and restoration.

RESUMO
Fungi generate different metabolites some of which are intrinsically bioactive and could therefore serve as templates for drug development. In the current study, six endophytic fungi namely Aspergillus flavus, Aspergillus tubigenesis, Aspergillus oryzae, Penicillium oxalicum, Aspergillus niger, and Aspergillus brasiliensis were isolated and identified from the medicinal plant, Silybum marianum. These endophytic fungi were identified through intra transcribed sequence (ITS) gene sequencing. The bioactive potentials of fungal extracts were investigated using several bioassays such as antibacterial activity by well-diffusion, MIC, MBC, anti-biofilm, antioxidant, and haemolysis. The Pseudomonas aeruginosa PAO1 was used to determine the antibiofilm activity. The ethyl acetate extract of Aspergillus flavus showed strong to moderate efficacy against Staphylococcus aureus, Escherichia coli, P. aeruginosa, and Bacillus spizizenii. Aspergillus flavus and Aspergillus brasiliensis exhibited significant antibiofilm activity with IC50 at 4.02 and 3.63 mg/ml, while A. flavus exhibited maximum antioxidant activity of 50.8%. Based on HPLC, LC-MS, and NMR experiments kojic acid (1) and carbamic acid (methylene-4, 1-phenylene) bis-dimethyl ester (2) were identified from A. flavus. Kojic acid exhibited DPPH free radical scavenging activity with an IC50 value of 99.3 µg/ml and moderate activity against ovarian teratocarcinoma (CH1), colon carcinoma (SW480), and non-small cell lung cancer (A549) cell lines. These findings suggest that endophytic fungi are able to produce promising bioactive compounds which deserve further investigation.
