Intradermal Sterile Water Injection: Safe and Effective Alternative for Relief of Acute Renal Colic in the Emergency Department.

BACKGROUND: The optimal pain relief method for acute renal colic in the emergency department remains controversial. OBJECTIVE: We compared the safety and efficacy of intradermal sterile water injection (ISWI) to treatment with intramuscular (IM) diclofenac, intravenous (IV) opioids, and IV paracetamol in patients with acute renal colic. METHODS: This randomized, single-blind study included 320 patients with renal colic to one of four treatment groups. The first group received ISWI at four different points around the most painful flank area. Patients in the DI, PARA, and TRAM groups received 75 mg IM diclofenac, 1 g IV paracetamol, and 100 mg IV tramadol, respectively. Pain intensity was measured using a visual analog scale (VAS) before treatment and 15, 30, and 60 min after treatment. RESULTS: VAS scores 15 and 30 min after treatment were significantly lower in group ISWI than in groups DI, PARA, and TRAM. However, there were no significant differences in the decrease in the pain score at baseline and at 60 min after treatment. In addition, fewer patients required rescue analgesia in group ISWI than in group TRAM. However, no significant differences were observed between group ISWI and group DI or PARA in terms of the need for rescue analgesia. Finally, there were significantly fewer adverse events in group ISWI than in groups DI and TRAM. CONCLUSIONS: ISWI had similar efficacy, faster pain relief, and lower need for rescue analgesia compared with diclofenac, paracetamol, and tramadol for the management of acute renal colic. In addition, ISWI was well-tolerated and had no adverse effects.

Ethnoveterinary uses of forage plants for domesticated ruminants in Malakand agency, Pakistan.

Plant ethnoveterinary uses are evident in various studies around the world, but the ethnoveterinary practices of forage species are not widely reported. Traditional knowledge is rapidly disappearing because of urbanization and commercial activities. The purpose of this study was to document plant species used by the local communities in Malakand Agency, Pakistan for foraging and ethnoveterinary purposes. Twenty different localities in the study area were surveyed for documentation of forage species and related traditional ethnoveterinary knowledge used for livestock. Semistructured questionnaires and field walks were used to conduct 67 interviews with local farmers and herdsmen. A total of 91 forage species from 26 families were documented, as well as their ethnoveterinary applications. Poaceae and Fabaceae were dominant families with 45% and 15% of species respectively. Among the forage species documented, 62 were highly palatable, 26 were moderately palatable and 12 were less palatable. The region's major veterinary diseases are flu, ringworms, inflammations, low milk production, constipation, bloat, mastitis, pneumonia and wounds. The 62 forage species were reported for the first time for various veterinary uses. This study revealed that local communities commonly use a diverse range of forage species in conjunction with indigenous knowledge of ethnoveterinary uses. These forage species have the potential to overcome the recent fodder shortage. Such studies will be beneficial to the commercial production of such forage species.

Augmentation of Cathepsin Isoforms in Diabetic db/db Mouse Kidneys Is Associated with an Increase in Renal MARCKS Expression and Proteolysis.

The expression of the myristoylated alanine-rich C-kinase substrate (MARCKS) family of proteins in the kidneys plays an important role in the regulation of the renal epithelial sodium channel (ENaC) and hence overall blood pressure regulation. The function of MARCKS is regulated by post-translational modifications including myristoylation, phosphorylation, and proteolysis. Proteases known to cleave both ENaC and MARCKS have been shown to contribute to the development of high blood pressure, or hypertension. Here, we investigated protein expression and proteolysis of MARCKS, protein expression of multiple protein kinase C (PKC) isoforms, and protein expression and activity of several different proteases in the kidneys of diabetic db/db mice compared to wild-type littermate mice. In addition, MARCKS protein expression was assessed in cultured mouse cortical collecting duct (mpkCCD) cells treated with normal glucose and high glucose concentrations. Western blot and densitometric analysis showed less abundance of the unprocessed form of MARCKS and increased expression of a proteolytically cleaved form of MARCKS in the kidneys of diabetic db/db mice compared to wild-type mice. The protein expression levels of PKC delta and PKC epsilon were increased, while cathepsin B, cathepsin S, and cathepsin D were augmented in diabetic db/db kidneys compared to those of wild-type mice. An increase in the cleaved form of MARCKS was observed in mpkCCD cells cultured in high glucose compared to normal glucose concentrations. Taken together, these results suggest that high glucose may contribute to an increase in the proteolysis of renal MARCKS, while the upregulation of the cathepsin proteolytic pathway positively correlates with increased proteolysis of MARCKS in diabetic kidneys, where PKC expression is augmented.

Correction of High-Grade Pseudogynecomastia After Massive Weight Loss: Modified Inferior Dermoglandular Pedicled Transverse Scar Reduction.

INTRODUCTION: Whereas body-contouring surgery after massive weight loss in women receives much attention, little attention has been devoted to accentuating the male physique. Male patients after massive weight loss often suffer from redundant skin and soft tissue in the anterior and lateral chest region, causing various deformities of pseudogynecomastia. The authors present their approach to high-grade pseudogynecomastia correction with preservation of the NAC on an inferior dermoglandular pedicle with transverse scar only closure and without any meaningful liposuction. MATERIALS AND METHODS: A description of comprehensive pseudogynecomastia correction with the aforementioned technique followed by review of 58 consecutive patients operated on in our clinic from January 2017 to June 2018. Epidemiological data such as age, weight, height, body mass index (BMI), weight loss, and the medical history of each patient were collected. All patients were photo-documented preoperatively and postoperatively in a standard manner. During the operation, weight of resected tissue and operative time were noted. RESULTS: Fifty-eight patients were operated on in a single stage. In our series, one patient had unilateral partial necrosis on nipple-areola complex, and two patients had minimal to moderate amounts of hematoma which were followed up without intervention. We did not encounter any infection-related complications or skin redundancy in our patients. Out of 58 patients, 55 of all the patients were highly satisfied with the aesthetic results. Three patients were mildly satisfied with the results, but they stress that moderate scar widening was the reason for the displeasure, not the definition of the chest which was deemed as satisfactory like the rest. CONCLUSION: Our technique obviates the need for skin resection in a second operation, allows immediate skin recontouring, and provides a viable nipple-areola complex at the desired location. The patient does not have to suffer prolonged stress while awaiting skin retraction and is protected from a second dose of anesthesia and hospitalization.

Heavy metal accumulation in the bark and leaves of Juglans regia planted in Artvin City, Turkey.

The aim of this study was to determine the level of heavy metals such as copper, iron, manganese, zinc, lead, nickel, cadmium and chromium concentrated in Juglans regia bark and leaf samples from different localities in Artvin, Turkey. Analysis of the heavy metals Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr in samples was carried out by inductively coupled plasma optical emission spectroscopy (ICP-OES; Perkin Elmer, Optima 8000 DV). Statistical significance was determined by analysis of variance (ANOVA). The comparisons were performed in order to determine whether there were any differences between J. regia bark and leaf samples in terms of average heavy metal accumulation levels. As a result of this study, the following mean concentrations were determined for J. regia bark samples: the contents of Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr (µg g-1, dry weight) ranged from 72.46 to 88.14, 14.40 to 628.0, 0.896 to 67.71, 7.000 to 28.52, 0.040 to 0.905, 1.031 to 2.744, 0.011 to 0.158 and 1.192 to 3.134, respectively. On the other hand, for J. regia leaf samples, the contents of Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr (µg g-1, dry weight) ranged from 0.339 to 13.80, 12.72 to 698.2, 1.001 to 204.6, 7.362 to 56.03, 0.158 to 0.665, 0.130 to 2.744, 0.041 to 0.114 and 0.508 to 2.767, respectively. In the statistical analysis, heavy metal accumulation values of J. regia bark and leaf samples for Cu, Ni and Cr were significantly different (P < 0.05).

Effectiveness of portfolio assessment in primary education: A multi-complementary research approach.

The current study represents a comprehensive exploration of the efficacy of portfolio assessment within primary school contexts, employing a Multi-Complementary Research (McA) framework comprising three distinct stages. In the pre-complementary knowledge stage, data collection commenced utilizing the document analysis method, concurrently conducting meta-analysis and meta-thematic analysis. From 18 studies, a meta-analysis of 23 datasets revealed a medium-level overall effect size. Simultaneously, meta-thematic analysis was conducted on 6 studies meeting specific inclusion criteria, analyzing themes and codes through content analysis. Transitioning to the post-complementary knowledge stage, an experimental study employing a pretest-posttest control group design was undertaken with third-grade primary school students. Additionally, thematic analysis based on participant perspectives was conducted. Subsequently, an eventual complementary knowledge stage was achieved by synthesizing findings from the initial two stages. Key themes emerged, titled "the effect of portfolio use in primary education on academic success, 21st century skills, and attitudes." The collective findings indicate that portfolio assessment in primary schools yields positive effects across all three identified themes.

Federated Multi-Label Learning (FMLL): Innovative Method for Classification Tasks in Animal Science.

Federated learning is a collaborative machine learning paradigm where multiple parties jointly train a predictive model while keeping their data. On the other hand, multi-label learning deals with classification tasks where instances may simultaneously belong to multiple classes. This study introduces the concept of Federated Multi-Label Learning (FMLL), combining these two important approaches. The proposed approach leverages federated learning principles to address multi-label classification tasks. Specifically, it adopts the Binary Relevance (BR) strategy to handle the multi-label nature of the data and employs the Reduced-Error Pruning Tree (REPTree) as the base classifier. The effectiveness of the FMLL method was demonstrated by experiments carried out on three diverse datasets within the context of animal science: Amphibians, Anuran-Calls-(MFCCs), and HackerEarth-Adopt-A-Buddy. The accuracy rates achieved across these animal datasets were 73.24%, 94.50%, and 86.12%, respectively. Compared to state-of-the-art methods, FMLL exhibited remarkable improvements (above 10%) in average accuracy, precision, recall, and F-score metrics.

Dysregulation of kidney proteases in the pathogenesis of hypertension following unilateral nephrectomy in juvenile mice.

BACKGROUND: Unliteral nephrectomy (UNX) results in the reduction of kidney mass. The remaining kidney undergoes compensatory renal growth via hypertrophy of the glomeruli and renal tubules to maintain a normal glomerular filtration rate (GFR). These compensatory mechanisms result in increased capillary pressure and glomerular hyperfiltration to increase single nephron GFR. Over time, hyperfiltration may lead to kidney scarring and the development of hypertension. OBJECTIVES: The first objective of this study was to test the hypothesis that a 50% reduction in functioning nephrons in juvenile mice leads to increased blood pressure over a 24-hour phase. The second objective was to test the hypothesis that UNX leads to changes in the expression and activity of kidney proteases in juvenile mice. METHODS: Eight male C57B6 juvenile wild-type mice were subject to UNX and an equal number of mice were subject to sham (SH) surgery. Metabolic cage studies were performed for 5 weeks to collect urine produced during the inactive and active phases. Blood pressure was measured using the tail cuff method twice weekly and tail blood was collected on different days during the inactive or active phase of each animal. The mice were euthanized at the age of 9 weeks. Western blotting and immunohistochemistry were performed to investigate changes in renal protein expression of various cathepsins and renal kallikrein 1 (KLK1) between the two groups. Protease activity assays were performed using kidney lysates and urine samples from each group. RESULTS: Compared to the SH group, UNX mice showed a persistent increase in blood pressure at week 3 which progressed toward the end of the study at week 5 of age. Cathepsin B, D, and S expression and activity were up-regulated in kidney cortex lysates from UNX mice compared to the SH control group. KLK1 protein expression was down-regulated and urinary nitric oxide excretion was decreased in UNX mice compared to the SH control group. CONCLUSION: UNX results in the development of persistent and progressive hypertension. Down-regulation of KLK1 and up-regulation of various cathepsins may contribute to the development of hypertension via multiple mechanisms including a decrease in nitric oxide (NO) production.

A distinctive presentation of diplopodia: a Y-metatarsal combining the extra foot and the extra digit of the main foot.

Diplopodia is a rare congenital anomaly and has been described as extra digits, metatarsals, and tarsal bones that form an extra foot or foot-like structure. Various skeletal deformities and anomalies involving other organ systems can accompany diplopodia. Treatment consists of surgery, splinting, and physical therapy, planned according to each patient's specific condition. We present a patient who had diplopodia with distinctive anatomic features (with postaxial polydactyly and without any anomaly of the tibia or fibula) compared with the previously reported cases, and concomitant anomalies, including left renal agenesis and anal atresia.

Computer-Based Intelligent Solutions for the Diagnosis of Gastroesophageal Reflux Disease Phenotypes and Chicago Classification 3.0.

Gastroesophageal reflux disease (GERD) is a multidisciplinary disease; therefore, when treating GERD, a large amount of data needs to be monitored and managed.The aim of our study was to develop a novel automation and decision support system for GERD, primarily to automatically determine GERD and its Chicago Classification 3.0 (CC 3.0) phenotypes. However, phenotyping is prone to errors and is not a strategy widely known by physicians, yet it is very important in patient treatment. In our study, the GERD phenotype algorithm was tested on a dataset with 2052 patients and the CC 3.0 algorithm was tested on a dataset with 133 patients. Based on these two algorithms, a system was developed with an artificial intelligence model for distinguishing four phenotypes per patient. When a physician makes a wrong phenotyping decision, the system warns them and provides the correct phenotype. An accuracy of 100% was obtained for both GERD phenotyping and CC 3.0 in these tests. Finally, since the transition to using this developed system in 2017, the annual number of cured patients, around 400 before, has increased to 800. Automatic phenotyping provides convenience in patient care, diagnosis, and treatment management. Thus, the developed system can substantially improve the performance of physicians.

Comparison of Hand-Wrist Findings of Rheumatoid Arthritis Patients According to the Use of Synthetic and Biological Disease-Modifying Antirheumatic Drugs (DMARDs): A Clinical, Radiographic, and Ultrasonographic Study.

OBJECTIVE: The aim of this study is to evaluate the hand-wrist findings in patients with rheumatoid arthritis (RA) using synthetic and a combination of synthetic and biological disease-modifying antirheumatic drugs (DMARDs) in terms of ultrasonographic, clinical, and radiographic data. METHODS: The study is designed as a cross-sectional study, and 31 RA patients followed up in the rheumatology outpatient clinic were enrolled. Nineteen patients were using only synthetic DMARDs, and 12 patients were using a combination of synthetic and biological DMARDs. The clinical data of each patient were recorded simultaneously. Disease Activity Score-28 (DAS-28) was used for the assessment of disease activation, and the Health Assessment Questionnaire (HAQ) score was used for the evaluation of general health status. Bilateral proximal interphalangeal (PIP), metacarpophalangeal (MCP) joints, and the radiocarpal, ulnocarpal, and midcarpal joints of the patients were examined by ultrasonography (US). The Sharp-van der Heijde modified score was used to determine the radiographic damage. RESULTS: There was no significant difference between the two groups in terms of demographic data, clinical findings, ESR, and CRP. When the groups were compared in terms of right and left PIP, MCP, and radiocarpal, ulnocarpal, and midcarpal synovitis grade total scores, no significant difference was found between the two groups. Radiographic total joint space scores were significantly lower in the group receiving only synthetic DMARD treatment (p=0.047) and 25-OH vitamin D levels were significantly higher (p=0.008). CONCLUSION: This study revealed that there was no significant difference between groups except radiographic total joint space scores.

Tempol treatment normalizes membrane expression of epithelial transport proteins in the kidney of salt-loaded hypertensive diabetic db/db mice.

OBJECTIVE: Hypertension exacerbates the progression and severity of diabetic kidney disease. In this study, we addressed the hypothesis that tempol acts at multiple segments of the nephron to normalize the abundance of sodium coupled epithelial transport proteins in the luminal plasma membrane to mitigate high blood pressure in salt-loaded hypertensive diabetic db/db mice. METHODS: Soluble and membrane fractions from freshly homogenized kidney cortex tissue samples were resolved by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and probed for specific proteins by Western blotting. Western blotting for specific urinary extracellular vesicle (uEV) markers and nanoparticle tracking analysis was performed to characterize each uEV preparation from each group. A one-way ANOVA was performed to determine statistical significance between three groups (hypertensive diabetic db/db mice treated with vehicle, hypertensive diabetic db/db mice treated with tempol, and wild-type mice). RESULTS: Tempol treatment reduced systolic blood pressure in hypertensive diabetic db/db mice compared to db/db mice that received vehicle. We observed attenuated membrane protein expression of the sodium hydrogen exchanger 3 (NHE3), sodium potassium chloride co-transporter (NKCC2), sodium chloride cotransporter (NCC), and epithelial sodium channel (ENaC) in the kidney of salt-loaded hypertensive diabetic db/db mice infused with tempol by osmotic minipump for 5 days compared to hypertensive diabetic db/db mice infused with vehicle. Also, the infusion of tempol in hypertensive diabetic db/db mice reduced the augmented protein expression of protein kinase c (PKC) epsilon observed in the vehicle treated hypertensive diabetic db/db kidney when compared to the healthy wild-type kidney. The amount of uEV and their size profiles were comparable between the three groups. CONCLUSIONS: This study demonstrates that tempol down-regulates epithelial transport mechanisms in each segment of the nephron and normalizes salt-induced high blood pressure in diabetic animals presumably in a PKC dependent manner.

Protective and therapeutic effects of licorice in rats with acute tubular necrosis.

OBJECTIVES: Various protective and therapeutic effects such as antioxidant, anti-inflammatory, anticancer, antihistaminic, and antibacterial effects have been depicted for licorice. However, its biological effects in the kidney are still not clear. Therefore, we aimed to investigate the efficiency of licorice in rats with gentamicin (GM)-induced acute tubular necrosis. DESIGN AND METHODS: Rats were randomized into the control group (only saline for 12 days), licorice group (licorice for 12 days), GM group (GM for 12 days), GM + licorice group, and licorice-treated GM group (licorice for 12 days after taking GM for 12 days). Blood urea, creatinine, and uric acid levels were measured and histopathological analyses of the kidneys were performed. The oxidative side of oxidant-antioxidant balance was evaluated by detecting lipid peroxidation (LPO) and total peroxide levels, and antioxidative side was determined by measuring total antioxidant capacity (TAC) and reduced glutathione (GSH) levels in plasma and kidney tissues. RESULTS: The oxidant-antioxidant balance seemed to be shifted to the oxidative side in the GM group when compared with the control and GM + licorice groups. In GM group, biochemical profiles showed a remarkable increase in blood uric acid, urea, and creatinine levels, and depletion of renal tissue and plasma TAC and GSH levels. In addition, histopathologic studies revealed severe acute tubular necrosis, congestion, and hyaline casts, verifying GM-induced nephrotoxicity. Licorice was effective in reduction of blood urea, creatinine, and uric acid levels, and also effective in decreasing the tubular necrosis score. Licorice treatment also significantly reduced LPO and total peroxide levels, and increased TAC and GSH levels in both renal tissue and blood. Moreover, these changes in rats subjected to the combined therapy (GM + licorice) were significantly less than those of GM group. CONCLUSIONS: Licorice ameliorates GM-induced nephrotoxicity and oxidative damage by scavenging oxygen free radicals, decreasing LPO, and improving antioxidant defense.

Impacts of Demographic and Clinical Characteristics on Disease Severity and Mortality in Patients with Confirmed COVID-19.

BACKGROUND: We investigated potential predictive factors for mortality and disease severity from demographic and clinical data, comorbidities, and laboratory findings in patients with confirmed COVID-19 who were consecutively admitted to our tertiary hospital. METHODS: In this retrospective, single-center, observational study, we enrolled consecutive 540 adult patients who had COVID-19 confirmed by a molecular method. Patients were categorized into three groups based on disease severity. Patients' demographic and clinical characteristics, mortality rates, and mortality-associated factors were analyzed. RESULTS: The overall mortality rate was 4.3% (23/540). Disease severity was mild in 40.9% (n = 221), severe in 53.7% (n = 290), and critical in 5.4% (n = 29) of the patients. There were significant differences among groups in terms of median white blood cell (WBC), hemoglobin, neutrophil, lymphocyte, and thrombocyte counts, as well as C-reactive protein (CRP), procalcitonin, lactate dehydrogenase (LDH), creatinine, albumin, D-dimer, ferritin, troponin, and fibrinogen levels. Furthermore, there were significant differences between surviving and non-surviving patient groups in terms of median WBC, hemoglobin, neutrophil, and lymphocyte counts, as well as CRP, procalcitonin, LDH, creatinine, albumin, D-dimer, and ferritin levels. CRP level (odds ratio [OR]: 1.020, 95% confidence interval [CI]: 1.009-1.032; p < 0.001), and CURB-65 score (OR: 4.004, 95% CI: 1,288-12,447; p = 0.017) were independently associated with disease severity and mortality. CONCLUSION: On admission, WBC, neutrophil, lymphocyte, and platelet counts can be used to predict disease severity in patients with COVID-19. CRP, ferritin, LDH, creatinine, troponin, D-dimer, fibrinogen, and albumin levels can also be used to predict disease severity in these patients. Finally, elevated CRP level and high CURB-65 score were predictors of disease severity and mortality.

Evaluation of toxicity potential of cobalt in wheat irrigated with wastewater: health risk implications for public.

The use of wastewater in irrigation weakens the beneficial properties of the soil and leads to a threat to food safety standards. The present research was designed to explore the cobalt toxicity associated with the ingestion of wastewater irrigated wheat. Wheat plants of five different varieties were collected from 7 different sites of Punjab, Pakistan, which were irrigated with three different sources of water. The sampling was done in two cropping years. The cobalt values in water, soil and wheat samples (root, shoot, grain) ranged from 0.46 to 1.24 mg/l, 0.15 to 1.20, 0.29 to 1.30, 0.08 to 0.76 and 0.12 to 0.57 mg/kg, respectively. All the water samples showed high cobalt concentration than the maximum permissible value. However, all the soil and wheat plant samples were found within the maximum allowable range. The high cobalt concentration in irrigating water showed that the continuous usage of such type of water may lead to cobalt toxicity in living organisms with the passage of time and may results in severe health risks.

Ecophysiological responses of some maquis (Ceratonia siliqua L., Olea oleaster Hoffm. & Link, Pistacia lentiscus and Quercus coccifera L.) plant species to drought in the east Mediterranean ecosystem.

The objective was to examine the adaptation strategies of four maquis species to drought prone environments; typical of the east Mediterranean area in degraded and healthy sites in Turkey. A comparison made between sites for Pistacia lentiscus and Quercus coccifera shows higher net daily photosynthesis in the degraded site, when compared with the healthy site; but Ceratonia siliqua and Olea oleaster exhibited no difference in their photosynthetic activity in environmentally contrasting conditions. The pattern of daily transpiration shows higher values in the degraded site in the case of P. lentiscus and Q. coccifera, while no site effect was observed for C. siliqua and O. oleaster. In the case of Q. coccifera, a behavior similar to C. siliqua was observed. A comparison made between C. siliqua and O. oleaster to observe seasonal differences in daily patterns of net photosynthesis and transpiration reveals that Q. coccifera had the highest water use efficiency (slope= 2.88; r2 = 0.61), followed by C. siliqua (slope = 2.74; r2 = 0.7), P. lentiscus (slope = 2.56; r2 = 0.52) and O. oleaster (slope = 2.40; r2 = 0.78). Olea oleaster and P. lentiscus performed as a drought tolerant species, being more resistant to aridity and thus indicative of the degradation state of the site. Ceratonia siliqua and Q. coccifera were found avoiding drought by adopting first a water-spending strategy, and then a water-saving strategy.

Biomonitoring of zinc and manganese in bark of Turkish red pine of Western Anatolia.

Turkish red pine (Pinus brutia) is a widespread evergreen tree in Mediterranean andAegean regions of Turkey. The barks of Pinus brutia were tested as a possible biomonitor of Zn and Mn accumulation studied in Western Anatolia, Turkey. Samples collected from industry roadside, suburban and rural areas from thirty locations in the study area were investigated. The concentration of zinc and manganese were determined in the bark of the red pine by atomic absorption spectrometry. As a result of this study the following mean concentrations were determined: for Zn between min 8.4 and max 14.1 microg g(-1), and for Mn between min 19.1 and max 24.0 microg g(-1). It was found that there is no affect of location on the element concentration of both Mn and Zn.

Health risk assessment through determining bioaccumulation of iron in forages grown in soil irrigated with city effluent.

The irrigation with sewage water can be useful if it has no negative effects on food crop yield, soil pollution, and health of humans. However, it includes various types of contaminants like heavy metals that pollute the soil and crops. In this regard, the aim of this study was to evaluate the possible health risks of heavy metals in forages. Forages both of summer and winter were grown with different water treatments (sewage water and tap water) in Department of Botany, University of Sargodha. The concentration of iron (Fe) in water, soil, and plant samples was determined. The Fe values in tap and sewage water were observed as 0.090 and 0.115 mg/L, respectively. The highest mean concentration of Fe was 9.608 mg/kg in the soil where Trifolium alexandrinum is grown, and the lowest mean concentration was 0.154 mg/kg which occurred in the soil where Trifolium resupinatum is grown in winter. The maximum mean concentration of Fe in the root samples of plants was observed as 2.483 mg/kg in Pennisetum typhoideum, and the minimum mean concentration occurred as 0.390 mg/kg in Zea mays grown in summer. The maximum bioconcentration factor value of Fe was observed for T. resupinatum (5.259) grown in winter. The maximum pollution load index value of Fe was observed for T. alexandrinum (0.1688). The maximum value of daily intake of metals was observed as 0.0731 in Medicago sativa, and the maximum health risk index value was determined as 0.1091 in P. typhoideum.

An ethnobotanical study in Midyat (Turkey), a city on the silk road where cultures meet.

BACKGROUND: Studies of ethnobotanical usages in south-eastern Turkey are rare. To widen this field of knowledge, we conducted an ethnobotanical study in Midyat (Mardin Province), Turkey. METHODS: The field study was completed during three years (2007-2010). Our aim was to document the ethnobotanical uses of local plants and to make an ethnobotanical inventory of uncommon plants using qualitative interviews. RESULTS: During field studies, 368 voucher specimens were collected in the investigated area. Ninety-two traditionally used plant species were reported from Midyat and surrounding vicinities in Turkey. Among the 92 taxa (129 usages), 35% were used for medical purposes, 22% for food, 13% for animal fodder, 7% as ornamental plants and dyes, 6% as brooms, 4% for latex and as fragrance, 4% for herbal tea, molasses and wine preparation, 3% for agricultural purposes, and 6% for other purposes. Comparative assessment showed that Teucrium polium (0.51), Matricaria aurea (0.26), Alcea setosa (0.21), and Malva neglecta (0.21) have the highest recorded UVs, and the following taxa had UVs between 0.10-0.20: Anthemis cotula (0.12), Allium cepa (0.13), Alcea striata subsp. striata (0.14), Crupina crupinastrum (0.12), Papaver rhoeas (0.13), Salvia multicaulis (0.14), Thymbra spicata (0.11), and Vicia pannonica subsp. striata (0.15). We reported the ethnobotanical usages of 21 taxa for the first time, in addition to indicating usages previously recorded in the literature. We also recorded four endemic plant usages in the area: Alkanna trichophila var. mardinensis, Centaurea kurdica, Centaurea stapfiana, and Sideritis libanotica subsp. linearis. They have variable leaf and flower morphology that are used traditionally. They are present as well-developed populations and thus their conservation status is not compromised. Additionally, Thymbra sintenisii is a recorded species that is classified as a rare and extensively used species in the region. CONCLUSIONS: These results contribute to the fundamental knowledge of ethnobotanical usages in Midyat. To date, ethnobotanical studies have not been carried out in this region. This investigation uncovered usages of endemic medicinal plant species and traditional knowledge of Midyat communities living in a mixed culture. The people of Midyat, Batman, and Sirnak are Turkish citizens from various ethnic backgrounds, such as Kurdish, Arabic, and Syriac. We compared our data with results from other studies conducted in Turkey, particularly in south-eastern and eastern regions, as well as with studies from bordering countries, Iraq, Jordan, Syria, and Iran. Nonetheless, more work needs to be conducted to extend the present knowledge for locals to contribute to and evaluate economic potential in the region.

Metal accumulation in Raphanus sativus and Brassica rapa: an assessment of potential health risk for inhabitants in Punjab, Pakistan.

Pakistan is an agricultural country and due to the shortage of clean water, most of the irrigated area (32,500 ha) of Pakistan was supplied with wastewater (0.876 × 109 m3/year). Concentrations of heavy metals in radish (Raphanus sativus) and turnip (Brassica rapa) taken from vegetable fields in Sargodha, Pakistan, were measured. Untreated wastewater was used persistently for a long time to irrigate these vegetable fields. A control site was selected that had a history of fresh groundwater irrigation. Mean metal concentrations were found for irrigation water, soil, and vegetables. In irrigation water, concentrations of Mo and Pb at three sites and Se at sites II and III were higher than the recommended limits. In vegetables, concentrations of Mo and Pb were above the maximum permissible limits. High bioconcentration factor was observed for Zn (12.61 in R. sativus and 11.72 in B. rapa) at site I and high pollution load index was found for Pb (3.89 in R. sativus and 3.87 in B. rapa) at site II. The differences in metal concentrations found in samples depended upon different soil nature and assimilation capacities of vegetables at different sites which in turn depended upon different environmental cues. The entrance of metal and metalloids to human body may happen through different pathways; however, the food chain is the chief route through which metals are transferred from vegetables to individuals. Health risk index observed for metals, (Mo, As, Ni, Cu, and Pb) higher than 1 indicated high risk through consumption of these vegetables at three sites.
