- Abstract
Background: This study was exclusively focused on the documentation and cross-cultural evaluation of ethnomedicinal knowledge (EMK) within the diverse linguistic groups of Kohistan situated between the Himalayan and Hindukush Mountain ranges in the north Pakistan., Methods: Data were gathered during the field survey (May 2022 to July 2023) through group conversations, semi-structured interviews, and on-site observation. Venn diagrams were employed to illustrate the comparative assessment of EMK, and different ethnobotanical indices were utilized to examine the data., Results: A total of 96 wild medicinal plant species (MPs) belonging to 74 genera and 52 botanical families were documented. The most reported MPs belong to the family Polygonaceae (11 species), followed by Asteraceae (9 species) and Lamiaceae (8 species). The ethnomedicinal uses of Leontopodium himalayanum, Pedicularis oederi, Plocama brevifolia, Polypodium sibiricum, Pteridium esculentum, Sambucus wightiana, Solanum cinereum, Teucrium royleanum, Rhodiola integrifolia, Aconitum chasmanthum were reported for the first time in this region. Among the reported taxa herbaceous species were dominated (72%), followed by trees and shrubs (17% and 10%, respectively). Digestive problems (40 taxa and 114 use reports) and skin disorders (19 taxa and 549 use reports) were the most cited disease categories, whereas M. communis, M. longifolia, Ajuga integrifolia, Ziziphus jujuba, and Clematis grata exhibited the highest percentage fidelity levels. Out of 109 documented medicinal uses, a mere 12 were shared across all linguistic groups, and Bateri emerges as a notable outlier with the highest number of medicinal uses. In addition, a significant homogeneity was noted in the reported botanical taxa (61 species) among different linguistic groups. However, since the last decade biocultural heritage of Kohistan is facing multifaceted risks that need urgent attention., Conclusion: Our findings could be valuable addition to the existing stock of ethnomedicinal knowledge and may provide ethnopharmacological basis to novel drug discovery for preexisting and emerging diseases prioritizing detailed phytochemical profiling and the evaluation of bioactive potential., (© 2024.

- Abstract
Objective: Disturbances in the oral mucosa is a major concern among patients undergoing chemotherapy. One of the most significant barriers in the implementation of oral care is the lack of knowledge. The aim of the study was to assess gingival and periodontal health status of chemotherapy patients before and after the provision of oral hygiene instructions., Methods: A single group, pre-post test was conducted to assess oral health status of patients at the daycare chemotherapy, Aga Khan University Hospital, Karachi, Pakistan. Oral hygiene instructions were given with study models and leaflets. Patients were followed for 6-weeks. Oral health was assessed by using Simplified-Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Differences in indices were analyzed in STATA version-15.0 using Generalized Estimating Equation (GEE) and Wilcoxon Signed-rank test., Results: Out of 74, 53 (72%) patients completed study follow-up. Improvement in the OHI-S was found in 14 (26%) patients (p-value < 0.001). GEE showed that age [adjusted OR = 1.10; 95% CI: 1.03-1.11], current chemotherapy cycle [adjusted OR = 1.19; 95% CI: 0.98-1.46], highest education level [Adjusted OR = 1.37; 95% CI: 1.08-12.7] and cancer therapy [Adjusted OR = 0.12; 95% CI: 0.24-0.55] were significantly associated with the change in OHI-S. Wilcoxon signed-rank test showed positive changes in the CPI (p-value < 0.001)., Conclusions: Basic oral hygiene instructional intervention can be effective in improving the oral hygiene of chemotherapy patients. Nurses should also play a key role in providing psychological and nutritional support to patients., (© 2024. The Author(s).)

- Abstract
Background and Ams: Despite the evident public health impact, the extent and patterns of alcohol use in the Eastern Mediterranean countries remain understudied. The latest estimation for the last 12-month use of alcohol in the region was 2.9% in 2016 by the World Health Organization. We reviewed the main indicators for alcohol consumption in the region since 2010., Methods: We systematically searched on-line databases until September 2023, together with other global and regional sources for studies on the adult general population (aged ≥ 15 years) and young general populations (aged < 18 years) and studies on the treatment-seeking individuals with substance use in Eastern Mediterranean countries. Studies were included from 22 countries: Afghanistan, Bahrain, Djibouti, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, United Arab Emirates and Yemen., Results: A total of 148 were included (n = 95 on the prevalence of alcohol use, n = 46 on the prevalence of alcohol use disorder, regular use and heavy episodic drinking, n = 35 on alcohol use pattern among people who use substances and one report on alcohol per capita consumption, n = 29 had data for more than one category). The pooled prevalence of the last 12-month alcohol use in the adult general population was 9.5% [95% confidence interval (CI) = 6.4-13.7] among males, 2.8% (95% CI = 1.3-5.5\) among females and 6.2% (95% CI = 3.9-9.6) in both sexes in the region, with notable subregional variations. Data on the prevalence of alcohol use disorder and heavy drinking were limited to several countries, with heterogeneous indicators. The pooled estimate of alcohol as the primary substance of use among treatment-seeking people who used substances was 16.9% (95% CI = 8.8-26.9)., Conclusions: More than 30 million adults in the Eastern Mediterranean region used alcohol in the last 12 months, with a prevalence of 6.2%. This is far fewer than the global estimate of 43% of the population aged 15 years and above, but is approximately two times more than the previous estimate (2.9%), reported by the World Health Organization in 2016, which might show an increasing trend., (© 2024 Society for the Study of Addiction.)

- Abstract
Background: Households are considered ideal settings for studying the transmission dynamics of an infectious disease., Methods: A prospective study was conducted, based on the World Health Organization FFX protocol from October 2020 to January,2021. Household contacts of laboratory-confirmed index cases were followed up for their symptomatic history, nasal swabs for RT-PCR,and blood samples for anti-SARS CoV-2 antibodies were collected at enrollment and days 7, 14 and 28. We estimated secondary attack rate (SAR), effective household case cluster size and determinants of secondary infection among susceptible household contacts using multivariable logistic regression., Results: We enrolled 77 index cases and their 543 contacts. Out of these, 252 contacts were susceptible at the time of enrollment. There were 77 household clusters, out of which, transmission took place in 20 (25.9%) giving rise to 34 cases. The acquired secondary attack rate (SAR) was 14.0% (95% CI 9.0-18.0). The effective household case cluster size was 0.46 (95%CI 0.33,0.56). Reported symptoms of nausea and vomiting (aOR, 7.9; 95% CI, 1.4-45.5) and fatigue (aOR, 9.3; 95% CI, 3.8-22.7) were associated with SARS-CoV-2 transmission., Conclusions: We observed a low SARS-CoV-2 secondary attack rate in the backdrop of high seroprevalence and asymptomatic transmission among households in Karachi, Pakistan., Competing Interests: Declaration of Competing Interest The authors have no relevant financial or non-financial interests to disclose., (Copyright © 2024.

- Abstract
Heavy metals (HMs) are extensively found in occupationally exposed miners and industrial workers, which may cause serious health-related problems to the large workforce. In order to evaluate the impact of these toxic pollutants, we have investigated the effect of cadmium (Cd), chromium (Cr), copper (Cu), and lead (Pb) concentration on exposed workers of mining, and woolen textile mill and compared the findings with unexposed individuals. From each category like exposed workers (mining, and woolen mill textile site) and unexposed individuals, 50 blood samples were taken. The occurrence of HMs in a sample was investigated through atomic absorption spectrometry while the oxidative stress marker malondialdehyde (MDA) and antioxidant enzyme statuses such as superoxide dismutase (SOD) and catalase (CAT) were analyzed in exposed and control samples. The results showed significant (p < 0.05) variation in Cd, Cr, Cu, and Pb levels in exposed and control samples. The concentration of Cd in the blood of WMWs, KMWs, and control group was 5.75, 3.89, and 0.42 μg/dL, respectively. On the other hand, the concentration of Pb in the blood of WMWs, MWs, and control was 32.34, 24.39, and 0.39 µg/dL while the concentrations of Cr and Cu in the blood of WMWs, MWs, and control group were 11.61 and 104.14 μg/dL, 4.21 and 113.21 μg/dL, 0.32 and 65.53 μg/dL, respectively. An increase in MDA was recorded in the exposed workers' group as compared to control subjects, whereas SOD and CAT activities decreased. Meanwhile, MDA was significantly and positively (p < 0.01) correlated with HMs, while negative significant correlations were found among HMs with SOD and CAT., (© 2023.

- Abstract
Background: The mountainous territory of Kohistan shelters diverse food plant species and is considered one of the important hotspots of local plant knowledge. In the era of globalization and food commodification, wild food plants (WFPs) play an important role in supporting local food systems and related local knowledge is one of the important pillars of food sustainability across the region. Since the area is populated by different cultural groups and each culture has retained particular knowledge on the local plant species, therefore, to make a cross-culturally comparison, the study was planned to record and compare the local plants knowledge among three linguistic groups viz Gujjar, Kohistani and Shina in order to not only protect the local knowledge but to determine the food cultural adaptations among these groups looking through the lens of their food ethnobotanies., Methods: Field ethnobotanical survey was carried out in 2020-2021 to gather the data on wild food plants. We used semi-structured interviews. Use reports were counted, and the results were visualized through Venn diagrams., Results: In total, 64 plant species belonging to 45 botanical families were documented. Among these Ajuga integrifolia, Barbarea verna, Clematis grata, Impatiens edgeworthii, Ranunculus laetus (vegetables), Parrotiopsis jacquemontiana (fruit), Indigofera tinctoria (flower), Juniperus excelsa, Primula elliptica, P. macrophylla (flavoring agent), Leontopodium himalayanum (Chewing gum), and Juniperus excelsa (snuff) were reported for the first time. The highest use reports (≥ 90) were recorded for Mentha longifolia, Amaranthus hybridus, Quercus semecarpifolia, Solanum miniatum, Oxalis corniculata, Ficus palmata, and Urtica dioica. Maximum number of wild food plant species (WFPs) were reported by Kohistani, followed by Shinaki and Gujjari linguistic groups. The percentage overlap of traditional knowledge on WFPs was highest among Kohistani and Shinaki (56.0%), followed by Shinaki and Gujjars (17.0%), and Kohistani and Gujjars (15.0%). Kohistani and Shinaki groups exhibited maximum homogeneity in traditional knowledge. However, Gujjars had more knowledge on WFPs compared to Kohistani and Shinaki. In addition, some dairy products viz. Bhorus, Bagora, Bak, Cholam, Kacha, Gurloo and Poyeen were reported also reported that are consumed orally and used in traditional cuisines., Conclusions: The study indicates that Kohistan is one of the important spots of biocultural diversity and could be recognized as biocultural refugia. WFPs have been an integral part of the traditional food systems among the studied groups, particularly the Gujjars have reported more distinct plant uses which could be referred to their distinctive ecological experiences among others. However, social change is one of the challenges that might lead to the erosion of local plant knowledge. Moreover, intercultural negotiations among the studied groups are also a matter of concern which could homogenize the local knowledge among them. Therefore, we suggest solid policy measures to protect the local knowledge and celebrate diversity across this mountain territory., (© 2023. The Author(s).)

- Abstract
This article describes the environmental impacts of producing a single seedling in forest nurseries of selected districts (i.e., Haripur, Abbottabad, and Mansehra) of Hazara Division of Khyber Pakhtunkhwa, Pakistan using the life cycle assessment (LCA) approach. This study was based on the cradle-to-gate approach which begins with the pre-nursery stage and progresses toward the main nursery before transplanting seedlings into the plantation site. Data or life cycle inventory (LCI) of seedling production were collected through questionnaire surveys and personal meetings with forest nurseries managers and workers regarding consumption of different inputs such as electricity, diesel, fertilizers, herbicides, and polyethylene bags, organic manure, and water consumption. The SimaPro software version 8.5 and the CML2000 v2.05 environmental model was applied to perform life cycle impact assessment (LCIA) for a single seedling production in forest nurseries in the study area. In line with the objectives of the study, primary data regarding inputs and outputs of the nurseries were collected from 35 nurseries in the study area by using a random questionnaire method. In addition, secondary data were taken from online databases such as Eco-invent v.3.2 CORRIM and peer-reviewed published literature. For this study, a functional unit of a single seedling was considered. Production weighted average data were modeled in the latest environmental modeling software i.e., SimaPro v.8.5 for ten US-EPA most wanted environmental impacts, such as global warming potential (GWP), abiotic depletion (AD), eutrophication potential (EP), acidification potential (AP), freshwater aquatic eco-toxicity (FAE), marine water eco-toxicity (MWE), terrestrial eco-toxicity (TE), ozone layer depletion (OLD), photochemical oxidation (PO), and human toxicity (HT). The results showed that the highest environmental impact posed by a single seedling was marine aquatic eco-toxicity (11.31360 kg 1,4-DB eq), followed by global warming potential (0.02945 kg CO2 eq) and (0.01227 kg 1,4-DB eq) human toxicity. The primary reason for these environmental burdens was the use of synthetic fertilizers in forest nurseries and the consumption of fossil fuels in nursery mechanization and transportation activities. The total cumulative energy demand for a single seedling was (0.800 MJ) with more than 90% contribution from fossil fuel energy resources such as petrol and diesel. It is therefore highly recommended to use renewable energy resources and organic fertilizers instead of chemical fertilizers in forest nurseries to avoid and minimize greenhouse gas emissions (GHS) and other toxic emissions in the study area.

- Abstract
Payment for ecosystem services (PES) is a mechanism where a consumer is able and ready to pay for the protection of the precise ecosystem service and there must be a provider such as local societies receiving an economic resource, who in return, must have the ability to maintain that ecosystem service. Economic valuation provides basis for payment for ecosystem services. Therefore, objective of this study was to evaluate tourism and carbon stock services of the Islamabad Capital Territory (ICT), Pakistan. Two forest zones (Chirpine and Scrub) of Islamabad capital territory (ICT) were selected for estimation of carbon stock and their carbon credits and carbon worth, a questionnaire-based survey was conducted for tourism as a payment for ecosystem services. The method for carbon stock assessment was systematic sampling for Chirpine forest whereas random sampling was done for scrub forest. The size of sampling plot was 17.84 m radius, and a total of 93 plots (49 Scrub zone and 44 Chirpine zone) was taken in the study area. The carbon stock of both zones (Chirpine and Scrub zone) is 22556.75 ton/ha (Chirpine 20105.79, Scrub 2450.96) and total carbon dioxide sequestered by both zone is 82557.72 ton/ha (Chirpine 73587.2, Scrub 8970.52), total carbon credits of both zone is 302160.87 (Chirpine 269328.97, Scrub 32831.9) and the carbon worth of both Chirpine and scrub zone is 4532418.92 $ (Chirpine 4039937.09$, Scrub 492481.83$). Similarly, from tourism point of view, in Shakar Parian, 94% tourists were agreed for PES whereas 6% were disagreed for the PES (the 6% tourist were disagreed to contribute for PES, 40% were agreed for Rs.5 contribution and 54% for Rs.10.). moreover, in Lake view Park, 97% tourists were agreed and 3% are disagreed (In Lake View Park 5% tourists were disagreed for the PES contribution whereas 32% were agreed for Rs.5 and 63% were for Rs.10). In Damen e Koh, around 87% tourist were agreed and 13% were disagreed, (24% were agreed for the contribution of Rs.5 and 63% tourists were agreed for the contribution of Rs.10). In Marghazar Zoo, 93% tourists were agreed (22% were agreed for contribution of Rs.5 and 71% tourist were agreed for contribution of Rs.10) and 7% are disagreed for PES whereas 7% tourists were not agreed for contribution. PES may implement to compensate forest and parks manager to ensure better management of the forests and parks. Due to prime location and scenic beauty of the ICT, it has huge potential for implementation of PES mechanism for sustainable forest management and conservation. Therefore, it is recommended that Capital Development Authority (CDA) Islamabad should devise a plan for implementation of PES in forests and parks of ICT for its sustainable management of recreational and forest resources.

- Abstract
Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration of PM in ambient air and its associated health risk in Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas and industries in Haripur city. Concentration of PM2.5 (µg/m3) and PM10 (µg/m3) was measured with Youngteng YT-HPC 3000A portable PM counter. The results revealed that values of both PM2.5 and PM10 were above the permissible limits (35 µg/m3 for PM2.5 and 150 µg/m3 for PM10) set by Environmental Protection Agency Pakistan (Pak-EPA) in all the educational institutes, hospitals, recreational areas and industries investigated. Furthermore, significant (p<0.05) variation was found in the concentration of both PM2.5 and PM10 in all the educational institutes, hospitals, recreational areas, and industries studied. The concentration of PM2.5 was positively correlated with the concentration of PM10 in all the sampling sites. Therefore, from 1-14 scale standard of health index, the values of PM2.5 and PM10 exhibited that the ambient air quality of Haripur city Pakistan is under high risk. If the regulatory authorities such as Environmental Protection Agency, Health Department and Local Government monitor PM pollution in different settings of Haripur city, then a decrease can be possible in the pollution level. The remedies that can be taken to overcome the problem of ambient air pollution such as PM are plantation of trees at the sites where there are higher levels of air pollutants and use of masks on personal protection basis along with implementation of pollution control system in industries of Hattar Industrial Estate Haripur city, Pakistan.

- Abstract
This study aimed to develop and evaluate data driven models for prediction of forest yield under different climate change scenarios in the Gallies forest division of district Abbottabad, Pakistan. The Random Forest (RF) and Kernel Ridge Regression (KRR) models were developed and evaluated using yield data of two species (Blue pine and Silver fir) as an objective variable and climate data (temperature, humidity, rainfall and wind speed) as predictive variables. Prediction accuracy of both the models were assessed by means of root mean squared error (RMSE), mean absolute error (MAE), correlation coefficient (r), relative root mean squared error (RRMSE), Legates-McCabe's (LM), Willmott's index (WI) and Nash-Sutcliffe (NSE) metrics. Overall, the RF model outperformed the KRR model due to its higher accuracy in forecasting of forest yield. The study strongly recommends that RF model should be applied in other regions of the country for prediction of forest growth and yield, which may help in the management and future planning of forest productivity in Pakistan.

- Abstract
Economic valuation of ecosystem services is a new concept in forest management. Economic valuation provides basis for payment for ecosystem services (PES). Therefore, objective of this study was to evaluate eco-tourism and carbon stock services of the Maindam valley, District Swat, Pakistan. For the carbon stock calculation, a sample size of 155 plots of 0.1 hectare (Ha) was taken using preliminary survey at 95% confidence interval and 10% allowable error. The data for tourism services was collected from owners of all the hotels, 100 tourists and key informants of the area at 10% sampling intensity on pretested questionnaire for twenty years period (1997-2017). Results showed that Miandam valley has carbon stock worth US$ 16,306,000 while the value of eco-tourism was US$ 1,578,458 on annual basis. The results also showed that trend of tourism has drastically declined after the 9/11 incident for foreigners and locals and the situation was further deteriorated during the era of Talibanization or militancy from 2008-2011. This study recommends implementation of PES strategy at the rate of 5%, thus a total of US$ 78,922 can be earned from eco-tourism and carbon crediting in the study area annually, which could play important role in sustainable forest management.

- Abstract
The present study was conducted for the taxonomic, morphometric and limnological assessment of the commercially important ichthyofauna of Sakhakot Stream, Malakand, Pakistan. The study area was divided into three sites along the water course namely Dargai Stream, Sakhakot Stream and Shergarh Stream. Fish samples were collected randomly during January to August 2017 with the help of fish gears. A taxonomic key was designed for the collected fish specimens. Ten fish species were identified belonging to 3 orders and 4 families. Family Cyprinidae was the dominant family with seven representative species while families Siluridae, Nemacheilidae and Mastacembelidae were represented by one species each. Lower mean total length and standard length was recorded in Puntius conchonius (Hamilton, 1822) as 9.2 ± 0.6 cm and 7.3 ± 0.6 cm respectively, while highest mean total length and standard length was recorded in Mastacembelus armatus (Lacepede, 1800) as 28.1 ± 1.7 cm and 15.9 ± 2.4 cm respectively. Mean pH of the water ranged from 6.1 at Shergarh Stream in August to 8.7 at Sakhakot Stream in January. Average temperature range was recorded from 10.9 °C in January at Dargai Stream to 18.7 °C in August at Shergarh Stream. No statistically significant difference was found for temperature (p = 0.96) and pH (p = 0.14) in the three water streams. The present study will provide a baseline for the rearing and enhancement of wild stock of the commercially important ichthyofauna in the field of aquaculture and fisheries.

Objective: To determine population-based estimates of coronavirus disease 2019 (COVID-19) in a densely populated urban community of Karachi, Pakistan., Methods: Three cross-sectional surveys were conducted in April, June and August 2020 in low- and high-transmission neighbourhoods. Participants were selected at random to provide blood for Elecsys immunoassay for detection of anti-severe acute respiratory syndrome coronavirus-2 antibodies. A Bayesian regression model was used to estimate seroprevalence after adjusting for the demographic characteristics of each district., Results: In total, 3005 participants from 623 households were enrolled in this study. In Phase 2, adjusted seroprevalence was estimated as 8.7% [95% confidence interval (CI) 5.1-13.1] and 15.1% (95% CI 9.4-21.7) in low- and high-transmission areas, respectively, compared with 0.2% (95% CI 0-0.7) and 0.4% (95% CI 0-1.3) in Phase 1. In Phase 3, it was 12.8% (95% CI 8.3-17.7) and 21.5% (95% CI 15.6-28) in low- and high-transmission areas, respectively. The conditional risk of infection was 0.31 (95% CI 0.16-0.47) and 0.41 (95% CI 0.28-0.52) in low- and high-transmission neighbourhoods, respectively, in Phase 2. Similar trends were observed in Phase 3. Only 5.4% of participants who tested positive for COVID-19 were symptomatic. The infection fatality rate was 1.66%, 0.37% and 0.26% in Phases 1, 2 and 3, respectively., Conclusion: Continuing rounds of seroprevalence studies will help to improve understanding of secular trends and the extent of infection during the course of the pandemic., (Copyright © 2021 The Authors.

- Abstract
Sustainability of the environment has become pivotal in the modern world, and there have been enormous efforts by the world leaders and organizations to reduce the effects of hazardous production on the environment. This has led companies to implement pro-environment programs and work on sustainability to shift consumption from conventional products to green products. This study incorporates green trust, environmental concerns, and intrinsic religious orientation as a moderator into the theory of planned behavior. It aims to validate the theory of planned behavior and its extended form to predict Pakistani consumers' eco-conscious behavior, and simultaneously assess the moderating effect of intrinsic religious orientation on consumers' attitude towards green products. The data for the study was collected from 300 respondents through purposive sampling from Karachi, the metropolitan city of Pakistan. Structural equation model (SEM) was applied to test the proposed hypotheses. The results of SEM indicate that all paths in the model are significant, except the path from attitude towards green products to eco-conscious behavior. The results also indicate that intrinsic religious orientation has no moderating effect on the green trust and attitude towards green products. This study contributes to understand the effects of new constructs in the theory of planned behavior and their relationship with other variables in the model. It also provides theoretical and managerial implications to academics and marketing professionals for understanding and promoting eco-conscious consumer behavior.

- Abstract
Achromatopsia (ACHM) is an early-onset retinal dystrophy characterized by photophobia, nystagmus, color blindness and severely reduced visual acuity. Currently mutations in five genes CNGA3, CNGB3, GNAT2, PDE6C and PDE6H have been implicated in ACHM. We performed homozygosity mapping and linkage analysis in a consanguineous Pakistani ACHM family and mapped the locus to a 15.12-Mb region on chromosome 1q23.1-q24.3 with a maximum LOD score of 3.6. A DNA sample from an affected family member underwent exome sequencing. Within the ATF6 gene, a single-base insertion variant c.355_356dupG (p.Glu119Glyfs*8) was identified, which completely segregates with the ACHM phenotype within the family. The frameshift variant was absent in public variant databases, in 130 exomes from unrelated Pakistani individuals, and in 235 ethnically matched controls. The variant is predicted to result in a truncated protein that lacks the DNA binding and transmembrane domains and therefore affects the function of ATF6 as a transcription factor that initiates the unfolded protein response during endoplasmic reticulum (ER) stress. Immunolabeling with anti-ATF6 antibodies showed localization throughout the mouse neuronal retina, including retinal pigment epithelium, photoreceptor cells, inner nuclear layer, inner and outer plexiform layers, with a more prominent signal in retinal ganglion cells. In contrast to cytoplasmic expression of wild-type protein, in heterologous cells ATF6 protein with the p.Glu119Glyfs*8 variant is mainly confined to the nucleus. Our results imply that response to ER stress as mediated by the ATF6 pathway is essential for color vision in humans.

- Abstract
Purpose: To investigate the molecular basis of retinitis pigmentosa in two consanguineous families of Pakistani origin with multiple affected members., Methods: Homozygosity mapping and Sanger sequencing of candidate genes were performed in one family while the other was analyzed with whole exome next-generation sequencing. A minigene splicing assay was used to confirm the splicing defects., Results: In family MA48, a novel homozygous nucleotide substitution in C8orf37, c.244-2A>C, that disrupted the consensus splice acceptor site of exon 3 was found. The minigene splicing assay revealed that this mutation activated a cryptic splice site within exon 3, causing a 22 bp deletion in the transcript that is predicted to lead to a frameshift followed by premature protein truncation. In family MA13, a novel homozygous null mutation in C8orf37, c.555G>A, p.W185*, was identified. Both mutations segregated with the disease phenotype as expected in a recessive manner and were absent in 8,244 unrelated individuals of South Asian origin., Conclusions: In this report, we describe C8orf37 mutations that cause retinal dystrophy in two families of Pakistani origin, contributing further data on the phenotype and the spectrum of mutations in this form of retinitis pigmentosa.

- Abstract
Different parts of Acacia nilotica (L.) Delile, Calotropis procera (Aiton) W.T. Aiton, Adhatoda vasica Nees, Fagoniaar abica L. and Casuarina equisetifolia L. are traditionally used in folk medicine for the treatment of a variety of common ailments like nausea, cold, cough, asthma, fevers, diarrhea, sore throat, swelling, etc. The present study was aimed to evaluate the anti-Helicobacter pylori and urease inhibition activities of extracts produced from the above selected medicinal plants native to Soon Valley (home to an old civilization) in the Punjab province of Pakistan. Methanol, acetone and water extracts of the plants were evaluated for anti-bacterial activity against thirty four clinical isolates and two reference strains of H. pylori. Minimum inhibitory concentrations (MICs) of the extracts were determined using the agar dilution method and compared with some standard antibiotics like amoxicillin (AMX), clarithromycin (CLA), tetracycline (TET) and metronidazole (MNZ), used in the triple therapy for H. pylori eradication. H. pylori urease inhibition activity of the extracts was assessed by the phenol red method, wherein, Lineweaver-Burk plots were used to determine Michaelis-Menten constants for elucidating the mechanism of inhibition. Methanol and acetone extracts from Acacia nilotica and Calotropis procera exhibited stronger anti-H. pylori activity than MNZ, almost comparable activity with TET, but were found to be less potent than AMX and CLT. The rest of the extracts exhibited lower activity than the standard antibiotics used in this study. In the H. pylori urease inhibitory assay, methanol and acetone extracts of Acacia nilotica and Calotropis procera showed significant inhibition. Lineweaver-Burk plots indicated a competitive mechanism for extract of Acacia nilotica, whereas extract of Calotropis procera exhibited a mixed type of inhibition.

- Abstract
To date, of 13 loci with linkage to non-syndromic autosomal recessive mental retardation (NS-ARMR), only six genes have been established with associated mutations. Here we present our study on NS-ARMR among the Pakistani population, where people are traditionally bound to marry within the family or the wider clan. In an exceptional, far-reaching genetic survey we have collected more than 50 consanguineous families exhibiting clinical symptoms/phenotypes of NS-ARMR. In the first step, nine families (MR2-9 and MR11) with multiple affected individuals were selected for molecular genetic studies. Two families (MR3, MR4) showed linkage to already know NS-ARMR loci. Fifteen affected and 10 unaffected individuals from six (MR2, MR6, MR7, MR8, MR9 and MR11) families were genotyped by using Affymetrix 5.0 or 6.0 single-nucleotide polymorphism (SNP) microarrays. SNP microarray data was visually inspected by dChip and genome-wide homozygosity analysis was performed by HomozygosityMapper. Additional mapping was performed (to exclude false-positive regions of homozygosity called by HomozygosityMapper and dChip) on all available affected and unaffected members in seven NS-ARMR families, using microsatellite markers. In this manner we were able to map three novel loci in seven different families originating from different areas of Pakistan. Two families (MR2, MR5) showed linkage on chromosome 2p25.3-p25.2. Three families (MR7, MR8, and MR9) that have been collected from the same village and belong to the same clan were mapped on chromosome 9q34.3. MR11 maps to a locus on 9p23-p13.3. Analysis of MR6 showed two positive loci, on chromosome 1q23.2-q23.3 and 8q24.21-q24.23. Genotyping in additional family members has so far narrowed, but not excluded the 1q locus. In summary, through this study we have identified three new loci for NS-ARMR, namely MRT14, 15 and 16., (© 2010 John Wiley & Sons A/S.)

We evaluated the distribution of ABO and Rhesus (Rh) D blood groups in the population of Poonch district in Azad Jammu and Kashmir. The blood group phenotypes were detected by the classic slide method. The ABO blood group system in the total sample showed the same trend of prevalence as for the general Indian subcontinent (B > or = O > A > AB). The same trend was found among males, but among females the order of prevalence was different (O B > A > AB). However, the allelic frequencies in both sexes were in the order of O > B > A. The Rh positive and negative distribution trend in both sexes was also similar.

- Abstract
Objective: To detect CTX-M phenotype utilizing disc diffusion and MIC testing in Escherichia coli isolated from a tertiary care urology setting., Methods: Fifty single, non duplicate ESBL producing isolates from a tertiary care urology hospital were evaluated for the presence of CTX-M phenotype. Initially all the urinary isolates were tested for ESBL production. The isolates were identified by using API 20E galleries and screened for ESBL production by combination disc methods. Representative 4 ESBL isolates were sent to Antibiotic Resistance Monitoring and Reference Laboratory (ARMRL), Health Protection Agency, Colindale, London, UK where those were further subjected to MIC testing by agar dilution and E-test strips., Results: A total of 4 ESBL producing E. coli isolates were characterized to be CTX-M on phenotypic characterization. The overall yield of CTX-M phenotypes was 75%., Conclusion: The emergence of CTX-M from Pakistan is alarming; however, further studies are required to study the epidemiology and genetic characterization of CTX-M types of ESBLs.

- Abstract
Localized autosomal recessive hypotrichosis (LAH) is rare disorder affecting the scalp, trunk and extremities and largely sparing the facial, pubic and axillary hair. Mutations in desmoglein 4 (DSG4) gene are responsible for LAH which maps to human chromosome 18q12. In this study a recurrent intragenic deletion mutation (Ex5_8del) was identified in DSG4 gene in two Pakistani families of Balochi and Sindhi origins. Manifestation of identical intragenic deletion mutation in eight Pakistani families, six reported earlier and two here, is exceptionally evocative of the dispersion of ancestral chromosome in different ethnic groups through common ancestors.

- Abstract
Background: This study was carried out to determine the aetiology, pattern and management of maxillofacial injuries at PIMS, Islamabad., Methods: This descriptive study was conducted at Plastic Surgery Department, PIMS Islamabad from 1st February 1998 to 30th April 2002. All the adult patients presenting with maxillofacial injures were included where as patients less than 12 years of age and only facial lacerations were excluded. Similarly isolated nasal bone fractures were also excluded because these patients were routinely managed by ENT department. Age, sex, presentation, aetiology, associated injuries and treatment modalities undertaken in these patients were recorded., Results: In 164 patients 254 fractures were noted. Most were male (86%), ranging in age from 13-71 years with a male to female ratio of 6:1 respectively. The most frequent (48%) cause noticed was road traffic accidents followed by assault. Mandible was the commonest to be involved in such injuries followed by maxilla. Most of the patients (32%) had associated facial injuries. Various treatment modalities were practiced., Conclusion: Maxillofacial fractures should be managed by open reduction and internal fixation as early as possible.

- Abstract
Nonspecific X-linked mental retardation is a nonprogressive, genetically heterogeneous condition that affects cognitive function in the absence of other distinctive clinical manifestations. We report here linkage data on a large Pakistani family affected by a form of X-linked nonspecific mental retardation. X chromosome genotyping of family members and linkage analysis allowed the identification of a new disease locus, MRX53. The defined critical region spans approximately 15 cM between DXS1210 and DXS1047 in Xq22.2-26. A LOD score value of 3.34 at no recombination was obtained with markers DXS1072 and DXS8081., (Copyright 2001 Wiley-Liss, Inc.)

- Abstract
Exposure to hepatitis C virus (HCV) and its effect on ALT levels was studied in 35 transfusion dependent cases of thalassaemia major. Twenty-one (60%) cases were anti HCV positive and also showed raised Alanine Transaminase (ALT) levels. Of 14 anti HCV negative, Hepatitis B Surface Antigen (HBs Ag) negative seven showed raised ALT levels, indicating the chances of acute viraemia. Thus there is an urgent need to start anti HCV screening on all blood donations.
