Evaluación de la calidad del aceite de semilla de Moringa concanensis extraído mediante disolvente y adición de enzimas
The composition and quality of the M. concanensis seed oil extracted through an aqueous-enzyme-assisted technique, using three commercial enzyme-mixtures (Natuzyme, Kemzyme, and Feedzyme) was compared to those of the control-, (without enzymes) and solvent-extracted oils. Aqueous enzyme-extracted M.concanensis seed oil content ranged from 23.54 to 27.46% and was significantly (P 0.05) variation in the contents of fiber and ash within the three extraction methods. However, the protein content of the meal obtained through the aqueous-enzyme and control methods was significantly (P 0,05) en el contenido de fibra y ceniza para los tres métodos de la extracción. Sin embargo, el contenido proteínico de la harina obtenido por métodos enzimáticos y el control sin enzimas fue significativamente menor (P < 0,05) que el de la harina obtenida después de la extracción por disolvente. Las diferencias en el índice de yodo (67.1-68.0 g /100 g of oil), densidad en 24 °C (0,865-0,866 g/mL), índice de refracción a 40 °C (1,4622-1,4627) y fracción insaponificable (0,69-0,76 %) no fueron significativamente diferentes para ninguna de las técnicas de extracción. Las extinciones específicas en 232 y 270 nm, el índice de peróxidos, el índice de p-anisidina, la acidez libre y el color de los aceites extraídos con enzimas fueron inferiores a los del aceite obtenido mediante extracción con disolvente. La composición en ácidos grasos de los aceites fue similar en todas los aceites encontrándose sólo pequeñas en los contenidos de ácido esteárico y linoleico. Respecto a los tocoferoles, el contenido en g-tocoferol fue similar en el control y en las extracciones con enzimas y significativamente más elevado (P < 0.05) que en el aceite extraído con disolvente, mientras que el contenido en a-tocoferol fue superior en el aceite extraído con disolvente
Comparison of Biodiversity and Abundance of Earthworms in Maize Croplands, Irrigated with Sewage and Canal Water of District Faisalabad, Pakistan
The diversity and richness of earthworms that were irrigated with canal (Chak 200 RB Lathianwala) and sewage (Chokera) water in the district of Faisalabad were determined from August to November 2020. For collection of specimens, hand picking and digging method was used and then preserved in formalin. AAS (Atomic absorption spectrophotometer) was used to check the concentration of heavy metals in both water and soil samples. Total 10 species were identified from Chak 200 RB Lathianwala and showed Shannon-Weiner Diversity Index (H\u27) =2.13, Evenness = 0.93 and Dominance = 0.07. The significant difference in abundance were determined (t = 7.7115, p = 0.0001 at p \u3c 0.05). Water and soil samples of sewage water had an acidic pH (5.960, 6.213), while water and soil samples of canal water had a basic pH (7.748, 7.867). The levels of total dissolved solids, electrical conductance, dissolved oxygen, and alkalinity of sewage water were lower than those of canal water except for total suspended solids, turbidity, and metals, viz. Cr, Ca, Pb, Co, Cd, Zn, and Mg. In sewage water irrigated soil, their concentrations were also higher than canal water irrigated soil, except for Mg. A significantly positive correlation coefficient was observed among temperature and abundance at both localities. Results showed that acidic pH and higher concentrations of pollutants alter the diversity and abundance of earthworms
Association of Wilms Tumor with Crossed Fused Renal Ectopia in Children: A Case Report
Introduction: Wilms tumor is the most common renal malignancy in children. The occurrence of Wilms tumor with various congenital genitourinary anomalies has been reported, particularly in horseshoe kidneys, hypospadias, disorder of sexual development, and double collecting system. However, Wilms tumor with crossed renal ectopia is a rare finding.
Case Description: We are reporting a case report of Wilms tumor in a 3-year-old girl who presented with a huge left flank mass with cross-fused renal ectopia. After the initial workup and triphasic computed tomography (CT) scan of the chest, abdomen, and pelvis for confirmation of diagnosis and metastasis, the patient underwent image-guided tissue biopsy followed by neo-adjuvant chemotherapy, left radical nephrectomy with separation of fused right ectopic renal moiety and adjuvant chemoradiation.
Practical Implication: This report shows an association of Wilms tumor with cross-fused renal ectopia, a rare combination. Unusual findings on imaging with unilateral flank mass should be considered as part of the differential diagnosis for this rare finding. Adjuvant chemotherapy and modern imaging helped delineate the anatomy and ease the surgery for safe resection, improving the overall outcome

Differentiation of Small Hepatic Hemangioma from Small Hepatocellular Carcinoma with Tri-Phasic Helical Computed Tomography Method
Background: Hepatocellular carcinoma (HCC) ranks second amongst all causes of cancer deaths globally. It is on a rise in Pakistan and might represent the most common cancer in adult males. Among women, HCC is the 7th most common cancer and 6th most common cancer related death. In Pakistan prevalence of HCC varies from 3.7%-16% of malignant tumors and most common cause of HCC is viral hepatitis B, C and D related cirrhosis. Pakistan contributes significantly to global burden of hepatitis C, which is a known risk factor for HCC, and has one of the highest prevalence rates (>3%) in the world. Objective: To find out the difference of small hemangioma from small hepatic cellular carcinoma by using tri- phasic helical Computed Tomography method. Methodology: In this descriptive study, among 81 patients of suspected hepatocellular carcinoma and hepatocellular hemangioma were selected with age and gender discrimination by convenient sampling, at Department of Radiology, UOL Teaching hospital Lahore Pakistan. 128 slice Computed Tomography Toshiba Aquilion machine was used. Results: Out of 81 patients collected with the suspicion of hepatic hemangioma and hepatocellular carcinoma , 41 were females and 40 were males who visited radiology department. It shows 50.6% were females and males were 49.4%. Out of 81 patients, 25 patients came with HHS and 31 were with HCC. 25.9% develop carcinoma on left side, 32.1% on right side, 6.2% on R/L side and remaining 35.8% were Nill. Out of 81 patients 8 develop carcinoma on anterior, 5 on both, 3 on caudate, 5 on lateral,13 on both 4 on middle, 7 on posterior, 6 on segment eight, 1 on segment 4, 1 on segment 7, 1 on segment 2 and remaining 36 sites were nill. 27.5% males develop HCC and 48.8% females develop HCC. Out of 81 patients 36.6% female patients develop HHS and 25.0% male patients develop HHS. Conclusion: In this study we conclude that females develop a large number of HCC and HHS than males. Hepatocellular carcinoma shows enhancement in early arterial and early washout phase while post-contrast images showing capsule-appearance which is relatively specific for HCC. On the other hand, HHS shows uniform enhancement in arterial phase and iso- or hyper-attenuating to liver parenchyma on delayed phase.

Emergency Angioembolization for Life-Threatening Haemorrhage in Wilms Tumour
Introduction: Renal artery embolization has been used in a palliative fashion for symptomatic relief of hematuria or flank pain in unresectable renal cell carcinoma in adults. There is limited data on using embolization for actively bleeding and unresectable tumours in the oncological pediatric population. Case description: A previously healthy, five-year-old boy with no significant past medical or surgical history presented to the clinic with gradually worsening abdominal distension associated with occasional abdominal pain, gross hematuria, and lethargy for four months. Diagnostic investigations showed an 18 cm left-sided metastatic (pulmonary) renal tumour (Wilms), which was deemed unresectable on imaging. Treatment was planned on SIOP-RTSG protocol. However, he became hemodynamically and vitally unstable with acute sudden distension of the abdomen on the left side after the first cycle of chemotherapy. Imaging showed active bleeding from an inferior branch of the left renal artery. Selective angioembolization was done, and chemotherapy was reinitiated with a patent left main renal artery. Following the fourth cycle of chemotherapy, he developed hemodynamic instability and abdominal pain; imaging revealed the resolution of pulmonary nodules and bleeding from the left renal artery (main); this was again embolized, and the patient was stabilized. The patient was operated on after optimization and complete resection of the mass was done with negative margins. On six months follow up, he is well. Practical implications: To the best of our knowledge, this is the first case where angioembolization has been done in conjunction with neoadjuvant chemotherapy to downsize a Wilms Tumor to achieve favourable outcomes. Continued research efforts are necessary to optimize strategies and improve the prognosis for pediatric patients, and this case is one of the prime examples
Malware Detection in Internet of Things (IoT) Devices Using Deep Learning
Internet of Things (IoT) devices usage is increasing exponentially with the spread of the internet. With the increasing capacity of data on IoT devices, these devices are becoming venerable to malware attacks; therefore, malware detection becomes an important issue in IoT devices. An effective, reliable, and time-efficient mechanism is required for the identification of sophisticated malware. Researchers have proposed multiple methods for malware detection in recent years, however, accurate detection remains a challenge. We propose a deep learning-based ensemble classification method for the detection of malware in IoT devices. It uses a three steps approach; in the first step, data is preprocessed using scaling, normalization, and de-noising, whereas in the second step, features are selected and one hot encoding is applied followed by the ensemble classifier based on CNN and LSTM outputs for detection of malware. We have compared results with the state-of-the-art methods and our proposed method outperforms the existing methods on standard datasets with an average accuracy of 99.5%.publishedVersio
Prevalence of active HCV infection among the blood donors of Khyber Pakhtunkwa and FATA region of Pakistan and evaluation of the screening tests for anti-HCV
Hepatitis C is a fatal liver disease caused by the hepatitis C virus. In this study, blood donors, from various districts of the KPK province and the federally administered tribal area (FATA) of Pakistan were tested for anti-HCV antibodies and HCV RNA by ICT (Immuno-chromatographic test), ELISA and RT-PCR. Out of the 7148 blood donors, 224 (3.13%) were positive for anti-HCV antibodies by ICT, 135 (1.89%) by ELISA while 118 (1.65%) blood donors had active HCV infection as detected by RT-PCR. We suggest that ELISA should be used for anti-HCV screening in public sector hospitals and health care units
The provenance and tectonic settings of the greywacke member of the late Neoproterozoic Hazara Formation Lesser Himalayas, Northern Pakistan : evidence from geochemistry and petrography
The petrographic and geochemical analysis of the greywacke horizon of the late Neoproterozoic Hazara Formation from the Hazara Mountains has been investigated to determine the provenance, tectonic settings and weathering history of the sediments. The Late Neoproterozoic Hazara Formation is a thick sedimentary sequence comprising of greywacke, shale, argillites, siltstone, and limestone. The greywackes are characterized by fine to medium-grained, moderately sorted and sub-angular to sub-rounded framework grains. They are rich in quartz, lithic fragments and clay minerals. The petrographic investigation of the greywackes categorized them as feldspathic greywacke in the QFR diagram. The quartz content is higher in sandstone and may reach to 70%, which indicates a weathered felsic source. Chemical Index of Alteration values of greywacke suggests that the source region has experienced highly weathering conditions with a warm and moist climate. Various geochemical interpretations, elemental ratios like Th/Sc, La/Sc,Th/Cr, and positive Eu anomalies indicate that the greywackes of the Hazara formation derived from a felsic source and were deposited within an active continental margin tectonic settings. The main source area of the sediments of the greywackes was located to south to southeast, which may possibly be the Aravali orogeny, central Indian craton and Bundelkhand craton. Finally, the geochemical data of the major elements point to a felsic igneous provenance for the greywacke
