The level and distribution of selected organochlorine pesticides in water of River Satluj Pakistan. BRAZ J BIOL 2023; 83:e246776. [PMID: 36629624 DOI: 10.1590/1519-6984.246776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 04/23/2021] [Indexed: 01/09/2023] Open
Abstract
The study was aimed to identify different environmental factors (selected organochlorine pesticides) affecting the river water of Satluj. River Sutlej is about 1400 kilometers long and its water is extensively used for irrigation in Punjab, located both in India and Pakistan, which was also a reason of dispute between both countries for its water share. The study area was divided into four zones, Sulemanki Zone, Islam Zone, Mailsi Syphone Zone and Panjnad Zone. Liquid Liquid Extraction (LLE) technique was used for the collected water samples followed by high performance liquid chromatography (HPLC) UV-Visible detector The current finding revealed that aldrin was not detected during summer period in water samples of SZ-1 (Sulemanki Barrage), SZ-2 and SZ-3 (Maisli Siphon) of the study area. Lindane and DDE were found more in the samples of sediments from the study area at SZ-4 ranging from 2.238-8.226 ppb and 4.234-6.876 ppb, respectively. Heaptachlor (in sediments) was found to be0.032-234 ppb only at SZ-4.Endosulfan concentrations in water (winter) at SZ-3 was 0.06 ppb and at SZ-4,it was 0.05 ppb; dieldrin in water (winter) at SZ-4 was 0.0314 ppb and heptachlor was detected at SZ-1 (0.0315 ppb) and SZ-2 (0.0310 ppb) in water during winter season, were reaching to the Maximum Concentrations Limits (MCL), while all other residues investigated were found below the MCLin all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious. Present findings revealed that although the organochlorine pesticides are banned for agricultural use in many countries, including Pakistan, their presence in various samples might be due to illegal use of these pesticides in the study area and its neighboring regions. The overall study area comprises of mainly urban, suburban and agricultural land being the largest cotton growing area of the country. There is a need to take serious steps to minimize water pollution caused by pesticides to achieve a healthy lifestyle.

Abstract
Abstract In the developed countries, the use of OCPs (organochlorine pesticides) has been banned. However, in South Asia several of them are still in use. In Pakistan and India a constant addition of OCPs into the atmosphere has been indicated by various researchers. In this study levels of selected organochlorine pesticide residues were assessed in sediment and biota collected from four (4) water reservoirs (3 Barrages & 1 Siphon) on the River Satluj Pakistan, along 231 miles (372 km) of River stretch which was further divided into 12 sampling sites. It was aimed to find out the levels of organochlorine pesticide (OCPs) residues in sediments and from selected fish species (Labeo rohita, Wallagu attu, Cyprinus carpio) of the River Satluj Pakistan. The Organochlorine residues (seven pesticides) present in samples of sediments and biota were investigated through multi residue method, using Gas Chromatograph (GC-ECD).In the current study, the concentration of DDT, was investigated in Wallago attu (0.786-3.987 ppb), Labeo rohita (0.779-4.355 ppb) and Cyprinus carpio (1.234-5.654 ppb). DDE was also found in Cyprinus carpio (1.244-6.322 ppb), Wallag attu (0.877-4.221 ppb) and Labeo rohita (2.112-5.897 ppb). Aldrin was not observed in Labeo rohita and Wallago attu. Currently, lindane and DDE was found predominately high in the sediments of study area at SZ-4 (Panjnad Barrage) ranging (2.238-8.226 ppb) and (4.234-6.876 ppb), respectively. Heaptachlor was found only at SZ-4 (Panjnad Barrage) from the sediments with concentration ranging (0.032-234 ppb). In short all other residues investigated were found below the MCL (maximum concentration level) in all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious.

Abstract
Metal complexes of drug are used to inhibit growth of pathogenic microorganisms and reduces drug resistance. Moxifloxacin is a dihydroquinoline-3-carboxylic acid 4th generation fluoroquinolone antibiotic that has tendency to bind with metal ions. In current study four moxifloxacin-metal complexes i.e. Moxifloxacin-sliver (Moxi-Ag), Moxifloxacin-rhodium (Moxi-Rh), Moxifloxacin-titanium (Moxi-Ti) and Moxifloxacin-rubidium (Moxi-Rb) have been synthesized and evaluated for antibacterial activities against resistant microorganisms along with antioxidant effects. The structure elucidation was carried out using FTIR, 1H- NMR and UV-Vis spectroscopy. Agar well diffusion method and DPPH (1, 1- dipheny1-2-picrylhydrazyl) methods were used to study the antibacterial and antioxidant activity respectively. Both 1H NMR and FTIR spectra clearly showed that Moxi-metal complexes are formed due to change in their carboxyl stretching band in IR, H-2 and H-5 peak position in 1H NMR. All the Moxi-metal complexes showed distinguished antibacterial effects against both Gram-negative and Gram-positive bacteria as compared to drug which was found resistant against many microorganisms. Moxi-Rb and Moxi-Ag metal complexes showed higher antioxidant activity (IC50 values range from 8.26 - 9.19 µg/ml) than Moxi-Ti and Moxi-Rh metal complexes (IC50 range from 11.23 - 14.65 µg/ml).

Abstract
Vaccination is not only a medical term rather it is framed under socio-cultural perspectives and debates as well. Human history is full of illnesses caused bacteria and viruses killing millions of people including children and adults. Technological development in the health sector enabled to combat pathogenic illnesses through different methods whereby vaccination is one of them. However, it is a dilemma that vaccination has faced many barriers including logistical but most importantly sociocultural and religious. In 2019, WHO revealed vaccine hesitancy as a leading threat to health throughout the globe even in the top 10. This study looks to analyze peer reviewed literature to explore barriers to vaccination. Methodologically, this is desk research and systematic review. Numerous databases were searched with key words and purposively studies were selected for this study. A total of 17 most relevant studies were sampled. Findings show that there are four major factors hindering vaccination. 1st cultural and ethnic background matters whereby religion and the belief system are predominant factors. 2nd awareness and educational variables are also there, for instance, it is noted that many people are not aware of vaccination process specifically in case of HPV vaccination. 3rd social media plays a pivotal role whereby misinformation internalizes negative attitudes and misperceptions about vaccines. 4th social media is a key dimension whereby disinformation and misinformation are communicated through platforms whereby some are intentionally circulated. It is suggested that culturally relativism perspective can be helpful in increasing vaccination percentages. It pertains to intervention through culturally approved methods, for example, sensitizing the ethnic backgrounds through their leadership. In addition, vaccination tracking, media campaigns, focus on school level education to include health related course can be helpful.

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 phenomenological study was conducted to explore the im- pacts of terminal illness on patients and familial relationships of couples in Pakhtun society. 36 terminally ill patients selected purposively were interviewed separately (24 male & 12 female patients) by the way of open-ended questions. Numerous themes were extracted following verbatim transcripts. All the participants explained the impacts of terminal illness on their social lives and the positive and negative aspects of their spousal relationship. Depression, anger and desperation were apparent in the terminal patients. Similarly bitterness, guilt, persistent sadness and loss were common in the patients and alternatively in their partners as explained by the patients. This research highlights adistinct viewpoint on the damaging influences which terminal illness can have on the marital rela- tionship. However it also recommends how to deal the situation in apositive manner by making adjustments required by the concerned disease. The findings indicate that social scientists need to confess and reply to the incredible psycho-social im- pacts that serious illnesses and related medical procedures can have on the patients and their families even in this modern era of advance technology. Advance social and psychotherapeutic techniques and socio-psychological support of partners can as- sist such patients to live with apositive life style till the end.

Abstract
Poverty, a multifaceted concept has been defined as: hunger; lack of shelter; being sick and not being able to see a doctor; having no access to a job; lack of freedom: fear for the future. Historically, people have migrated from one place to another to increase their livelihood and improve the living standards of their left behind families, while the process of globalization has intensified the movement of people across the world. Although, migration has been an important source of remittance and help in socioeconomic uplift of migrant families, however; it has also negatively impacted migrants and their families. Migrants are exposed to different risks and vulnerabilities at their destinations, which exposes them to many other health problems including their exposure of contracting HIV/AIDS. This study was conducted in the District Lower Dir of Khyber Pakhtunkhwa province of Pakistan with the objectives to know the relationship between poverty, migration and transmission of HIV/AIDS. The study was qualitative in nature while the selection of the sample has been made under the purposive sampling technique. Primary data was collected from 12 respondents through in-depth interview using interview guide. The collected information was analyzed thematically in order to clarify the issue under study. The study concluded that migrants: face unsafe environments; lesser access to information and health services; precarious working and living condition; exposure to risky behaviors which put them at risk of contracting the disease.

Abstract
The epidemic of HIV/AIDS has devastating impacts on many societal features of both urban and rural communities. Cultural factors have been played a significant role in human decision making and behavior around health. In simple terms, culture basically refers to the traditions and customs upheld by societies and communities because of their belief systems and values, which guide their decisions and shape their thinking, actions, attitudes and behaviors. The role of culture has been of particular significance both in the transmission of HIV/AIDS. Certain cultural practices such as: gender inequalities; unequal access to health care services; injectable drug users; unequal access to economic resources and opportunities; and male dominancy contribute to the spread of HIV/AIDS. The current study aims to investigate how various cultural factors contribute in the transmission of HIV/AIDS. The study was conducted in Malakand Division of Khyber Pakhtunkhwa province, while using a qualitative approach. Further, primary data was collected from 15 respondents through in-depth interview (using interview guide) while the selection of the sample was made through non-probability sampling using purposive sampling techniques. The collected information was qualitatively analyzed and a thematic discussion has been made for better understanding of the issue. The researchers also suggests some remedies.

Abstract
Raphanus sativus L. (Brassicacae) possesses numerous health benefits due to presence of a host of secondary metabolites in its various parts. The present study investigated the nutritive value of Raphanus sativus (RS) seeds and seed oil. Proximate and physico chemical analysis were carried out by official AOAC (Association of Official Analytical Chemists) and AOCS (American oil chemist society) methods. Scanning electron microscopy (SEM) together with energy dispersive X-ray spectroscopy (EDS) described the surface morphology along with atomic elemental composition of the sample. Mineral contents were evaluated by Atomic absorption spectroscopy. Moisture content was 8.67±0.08% whereas protein, crude fiber, crude fat, carbohydrates, total ash values were reported as 20.13±0.15%, 7.86±0.15%, 32.27±0.25%, 27.32±0.85%, 3.75±0.02% respectively. EDS determined carbon, oxygen, magnesium, sulfur and potassium in seeds. All physico-chemical properties varied insignificantly for the two extraction methods, except for acid value and unsaponifiable matter, which were higher for Soxhlet's extracted oil than cold pressed oil. The mineral composition revealed potassium in the highest concentrations in seeds and seed oil i.e.1660.65±69.26 ppm and 47.80 ± 7.02 ppm respectively. The study suggested that the seed and seed oil could be a potential source of naturally originated raw material for the nutritive and pharmaceutical aid.

Abstract
Risperidone is an atypical antipsychotic agent clinically used to treat schizophrenia, bipolar diseases, and autism. Usually, the frequency of doses is twice daily. In the present study, risperidone controlled release matrices formulated using hydrophilic and hydrophobic polymers. The tablets were prepared by direct compression. The pre-compression and post-compression properties were assessed, along with swelling studies. The morphology of particles observed using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The stability study on the drug was performed using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). The optimized formulation was prepared with the help of hydrophilic polymer K100M (40% ratio). Furthermore, release kinetics had investigated. The release pattern of optimized formulation FT5 fitted best to zero-order kinetics and showed excellent release characteristics. The model-independent approach had been used, formulations FT6 and FT8 showed resemblance with FT5 in all three media, respectively. The once daily formulation of risperidone could be beneficial for schizophrenia patients and their caregivers and will improve patient compliance.

Abstract
Oxytropis glabra DC. is a plant with enormous therapeutic vitality. In the present study a comparison of lipophilic profiling of different parts of O. glabra has been carried out by using gas chromatography-mass spectrometry. A total of 32 compounds have been identified from this plant, amongst which 31 have been identified for the first time. These compounds have been further confirmed from their Van den Dool and Kratz (I) Indices. Out of these 32 compounds, 18 have been identified from flower (80.94%), 15 from fruit (85.36%), 11 from leaves (66.35%) and 11 from root (45.96%). The major class of metabolite identified from different parts is fatty acid. Hydrocarbons have also been detected in flower and fruit but not in root and leaves. The extracts were screened for their immunomodulatory activity on whole blood cells. The root oil was found to be moderately active (IC50 32.3 μg/mL). At present only limited data is available on the phytochemical composition of O. glabra.

Abstract
Efficient delivery of cytidine analogues such as Azacitidine (AZA) into solid tumors constitutes a primary challenge in epigenetic therapies. We developed a di-block nano-vector based on poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) for stabilization of the conjugated AZA under physiological conditions. With equimolar drug content, our nano-conjugate could elicit a better anti-proliferative effect over free drug in breast cancer both in vitro and in vivo, through reactivation of p21 and BRCA1 to restrict cell proliferation. In addition, we applied single-molecule fluorescence tools to characterize the intracellular behavior of the AZA-PLGE-PEG nano-micelles at a finer spatiotemporal resolution. Our results suggest that the nano-micelles could effectively enrich in cancer cells and may not be limited by nucleoside transporters. Afterwards, the internalized nano-micelles exhibit pH-dependent release and resistance to active efflux. Altogether, our work describes a delivery strategy for DNA demethylating agents with nanoscale tunability, providing a cost-effective option for pharmaceutics.

Abstract
This study was conducted with the aim to determine the pharmacokinetic and bioequivalence of diclofenac potassium 50 mg test (F4) tablet formulation with reference product (Caflam). Present study was single dose, randomized, two phase cross over design, conducted in 12 healthy Pakistani volunteers and planned in accordance with FDA guidelines. In this study a simple, selective, sensitive and reproducible HPLC procedure was developed and validated for the estimation of diclofenac potassium in plasma. The process was validated in the range of 50 - 0.05 µg.mL-1 and used in bioequivalence trial of two products. Multiple blood samples were collected at various time points (0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12 and 14 hr after treating volunteers with test (F4) and marketed reference brand. Plasma separation and deproteination were carried out with acetonitrile; samples (20µL) were injected using the validated HPLC method. Various pharmacokinetic parameters (compartmental and noncompartmental) were estimated using KineticaTM 4.4.1 (Thermo Electron Corp. USA). Bioequivalence among the products was established by calculating the 90% CI with log and non log transformed data for Cmaxcalc, Tmaxcalc, AUC0-∞, AUCtot and AUClast using two way ANOVA and Schirmann's Two one sided t- test. No significant difference was found between log and non-log data. The 90% confidence interval values using log transformed data for AUC0-∞ (0.997-1.024), AUCtot (1.004-1.031), AUClast (0.997 -1.024), Cmaxcalc (0.994-1.007) and Tmaxcalc (0.996-1.013) for the trial and reference products were found within the FDA acceptable limits of 0.8-1.25. Results were further verified by the Schirmann's one-sided t test. Results showed the bioequivalence of test and reference formulations. Both the products were well tolerated.

Abstract
In this study, we developed and characterized a delivery system for the epigenetic demethylating drug, decitabine, to sensitize temozolomide-resistant human glioblastoma multiforme (GBM) cells to alkylating chemotherapy. A poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) based nanoconjugate was fabricated to encapsulate decitabine and achieved a better therapeutic response in GBM cells than that with the free drug. After synthesis, the highly efficient uptake process and intracellular dynamics of this nanoconjugate were monitored by single-molecule fluorescence tools. Our experiments demonstrated that, under an acidic pH due to active glycolysis in cancer cells, the PLGA-PEG nanovector could release the conjugated decitabine at a faster rate, after which the hydrolyzed lactic acid and glycolic acid would further acidify the intracellular microenvironment, thus providing positive feedback to increase the effective drug concentration and realize growth inhibition. In temozolomide-resistant GBM cells, decitabine can potentiate the cytotoxic DNA alkylation by counteracting cytosine methylation and reactivating tumor suppressor genes, such as p53 and p21. Owing to the excellent internalization and endolysosomal escape enabled by the PLGA-PEG backbone, the encapsulated decitabine exhibited a better anti-GBM potential than that of free drug molecules. Hence, the synthesized nanoconjugate and temozolomide could act in synergy to deliver a more potent and long-term antiproliferative effect against malignant GBM cells.

Abstract
BACKGROUND Seventeen 1,4-dihydroquinoline-3-carboxamide and 1,4-dihydroquinoline-3-carbohydrazide derivatives of gatifloxacin have been prepared with a facile one step synthesis aiming to improve antibacterial, antifungal and immunological activities. The methodology allows the introduction of a variety of substituents such as amines, alcohol, phenol, amides and alkyl halides into the core structure of gatifloxacin. RESULTS The analog N-(3-aminophenyl)-1-cyclopropyl-6-fluoro-8-methoxy-7-(3-methylpiperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxamide has been identified as a potentially excellent anti-inflammatory agent, which exhibited highly potent effects on the oxidative burst activity of whole blood phagocytes (IC50 <12.5 μg mL-1), neutrophils (IC50 <0.1 μg mL-1) and macrophages phagocytes (IC50 <3.1 μg mL-1) as well as potent T-cell proliferation inhibitory effect (IC50 3.7 μg mL-1) while having comparable antibacterial activity to gatifloxacin. Another analog, 1-cyclopropyl-6-fluoro-8-methoxy-7-(3-methylpiperazin-1-yl)-4-oxo-N-phenyl-1,4-dihydroquinoline-3-carbohydrazide has tremendous T-cell proliferation inhibitory effect IC50 <3.1 μg mL-1 as compared to prednisolone, whereas, 3,5-dihydroxyphenyl1-cyclopropyl-6-fluoro-8-methoxy-7-(3-methylpiperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate and 2-hydroxyphenyl-1-cyclopropyl-6-fluoro-8-methoxy-7-(3-methylpiperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate envision good inhibitory activity on T-cells proliferation (IC50 6.8 & 8.8 μg mL-1 respectively). CONCLUSIONS The structural modification at carboxylic group has resulted in improved anti-inflammatory activities with comparable antibacterial activity to gatifloxacin. We believe that C3 structural modifications of gatifloxacin are definitely important in bringing major immunomodulatory changes in these compounds.

Abstract
A simple reversed phase HPLC method was developed for the quantitative determination of gatifloxacin (GTX) in the bulk material, pharmaceutical formulations and human serum using Mediterranea C18 (25 x 0.46 mm, 5 mm) column. The mobile phase, acetonitrile, methanol and water (40:40:20 v/v pH 2.7 adjusted by phosphoric acid), was delivered at a flow rate of 1.0 ml/min. The eluent was monitored using spectrophotometric detection at 286 nm. The method is specific to GTX and able to resolve the drug peak from formulation excipients and metal impurities. The method is accurate (99.18-101.87%), precise (intra-day variation 0.14-1.67% and inter-day variation 0.32-1.80%) and linear within the range 0.1-25 microg/ml (R2=0.999) concentration and was successfully used in monitoring left over drug in drug-metal complexes. The detection limit of GTX at a signal-to-noise ratio of 3 was 1.73 ng/ml in human plasma while quantification limit in human serum was 5.77 ng/ml. The proposed method is applicable to routine analysis of GTX in pharmaceutical formulations as well as in human plasma samples.

Abstract
Two new terpenoids, bakayanolide (1) and 2α-hydroxy-3β-methoxy-6-oxo-13α,14β,17α-lanosta-7,24-dien-21,16β-olide (2), together with the known compounds 6β-hydroxy-3-oxo-13α,14β,17α-lanosta-7,24-dien-21,16β-olide (3), sendanolactone (4), kulactone (5), and β-sitosterol have been isolated from the ethanolic root extracts of Melia azedarach. Triterpenoids (4), (5), and β-sitosterol have been identified previously from M. azedarach, while it is the first instance of the isolation of (3) from this source. The identity of these compounds was established through extensive spectroscopic methods (infrared and mass spectroscopy, 1H and 13C nuclear magnetic resonance) as well as appropriate two-dimensional nuclear magnetic resonance experiments. Bakayanolide (1) belongs to the rare class of C11 odd terpenes. Compounds (3) and (4) possessed moderate cytotoxic activity against KB cell lines.
