Cancer is one of the most extreme medical conditions in both developing and developed countries around the world, causing millions of deaths each year. Chemotherapy and radiotherapy are critical treatment approaches, but both have numerous adverse health effects. Furthermore, the resistance of cancerous cells to anticancer medication leads to treatment failure. The rising burden of cancer overall requires novel, efficacious treatment modalities. Natural medications offer feasible alternative options against malignancy in contrast to western medicines. Furanocoumarins’ defensive and restorative impacts have been observed in leukemia, glioma, breast, lung, renal, liver, colon, cervical, ovarian, and prostate malignancies. Experimental findings have shown that furanocoumarins activate multiple signalling pathways, leading to apoptosis, autophagy, antioxidant, antimetastatic, and cell cycle arrest in malignant cells. Additionally, furanocoumarins have been shown to have chemopreventive and chemotherapeutic synergistic potential when used in combination with other anticancer drugs. Here, we address different pathways which are activated by furanocoumarins and their therapeutic efficacy in various tumors. Ideally, this review will trigger interest in furanocoumarins and their potential efficacy and safety as cancer-lessening agents.
Various types of security attacks are normal in vehicular communication networks. The current study uses a support vector machine to implement a Point to Point Critical Path Monitoring (P2PCPM) based Denial of Service (DOS) Attack detection technique for Vehicular Communication Network (VCN) resource management. Greatest quality of P2PCPM is that it eliminates attacked nodes from the network for the smooth process of vehicular communication. This scheme works well in terms of accuracy as well as attack detection rate. The whole simulation is made and tried by utilizing MATLAB Software. Simulation result shows 99% accuracy in case of security attack detection as well as reduced training and testing error upto 2%. Experimental results indicate that this scheme has a great efficiency and works well up to 1000 nodes, which is the limitation of current implementation. In future, simulation test may be done for unlimited nodes using similar or other techniques of attack detection.
The aim of the study was to explore the inhibition and modulation of calcium oxalate monohydrate crystals into calcium oxalate dihydrate by phytic acid. The study was carried out on glass slides using phytic acid (1 - 5%) solutions. All tested solutions inhibited the growth and modulated calcium oxalate monohydrate crystals. Donuts, rosettes and X-shape crystals of calcium oxalate monohydrate along with their defected forms were observed. The presence of calcium oxalate dihydrate crystals as elongated rods and tetragonal bipyramidal crystals revealed the modulated forms of calcium oxalate monohydrate. Smaller zones of nucleation are declared as general patterns of growth inhibition. This study gives valuable information about calcium oxalate crystals' inhibition and modulation patterns. Further studies are required to confirm the results of the present study.
A simple and rapid RP-HPLC method has been developed and validated for the simultaneous determination of Levocloperastine fendizoate and Chlorpheniramine maleate syrup formulation. Resolution of the analytes was achieved within 10min, employing a mixture of 10mM mobile phase Buffer (pH 6.5): Acetonitrile (50:50, % v/v) as isocratic mobile phase, pumped at 1.0mL/ min through a C18 column (5μm particle size). The detection wavelength for the analytes was 227nm. The system suitability parameters were found to be acceptable. The linearity of response (r2>0.999) in the appropriate ranges (from 50% up to 150% of the expected concentrations of the analytes in the formulations), method accuracy (RSD<2.0%), repeatability and intermediate precision (RSD<2.0%), were confirmed. Robustness result indicates that the methods performance can withstand small variations in method parameters. Satisfactory results obtained in terms of analyte recovery and RSD, while analyzing marketed pharmaceutical preparations. Hence the method can be useful for regular analysis of this combination in marketed syrup formulation.
Background and Objective: The COVID-19 pandemic affected medical care systems including stroke care, globally. In this study, we investigated the impact of the COVID-19 outbreak on stroke care in Hadramout, in terms of rate of admission, access to care, risk factors, clinical presentation, and outcome. Materials and Methods: A hospital-based cross-sectional study comparing all stroke patients admitted to Ibn-seena University Hospital (ISTH), Mukalla, Hadramout, during two periods, May 1–October 31, 2020, during the pandemic of COVID-19 (COVID-19 group), and from May 1 to October 31, 2019 (pre-COVID-19 group). Data collected from patients’ medical record files into a master sheet, and were processed by the Statistical Package for Social Sciences software. Results: There were 117 stroke patients admitted in COVID-19 pandemic in 2020, and 213 patients admitted in the same period in 2019. Stroke admission declined by 45.1% (Odds Ratio [OR]=0.30, 95% confidence interval [CI] [95% CI]: 0.22–0.42, p<0.0001) with no age and sex differences. Hypertension (HTN) and diabetes mellitus were more frequent in COVID-19 group than the pre-COVID-19 group (OR=1.74, 95% CI: 1.08–2.80, p=0.02) and (OR=1.81, 95% CI: 1.14–2, 88, p=0.01), respectively. No significant difference in other risk factors was found. Patients in COVID-19 group arrived the hospital more late than the patients in pre-COVID-19 group (OR=2.63, 95% CI: 1.64–4.21, p<0.0001). Dysphasia and altered consciousness including coma were more common in COVID-19 group compared with pre-COVID-19 group (OR=4.5, 95% CI: 2.18–9.08, p<0.0001) and (OR=3.2, 95% CI: 2.00–5.12, p<0.0001), respectively. Hospital stay was greatly reduced among COVID-19 group as compared with pre-COVID-19 group (02.9±0.31 days vs. 8.6±0.92 days, p<0.0001) Mortality rate was higher among COVID-19 group than the pre-COVID-19 group (41.9% vs. 27.2%, p=007). Conclusion: The number of stroke patients admitted during the COVID-19 pandemic decreased, they arrived late and spent shorter hospital stays while having higher rates of HTN, diabetes, and impaired consciousness with a high mortality rate.
Increasing presence of women in economic pursuits like entrepreneurship activities is believed to be the result of development policies. This belief ignores the role of socioeconomic factors in the growth and development of women entrepreneurship.

Majority of the respondents started their business or service to become independent and to meet the financial needs of their family. From the study it has to be found that majority of the women find it difficult to manage their work and family and they are trying to overcome these difficulties by time management and with the help of their family members.
The skin provides an effective barrier and only limited number of drugs can penetrate in adequate amounts. This study aims to identify the relationship between the physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs in view of their feasibility to transdermal delivery. Biphenylacetic acid, diclofenac base, diclofenac sodium, indomethacin and piroxicam are the drugs studied. Number of physicochemical properties studies were performed. Drug permeation studies across hairless mouse skin were carried out using an in-vitro finite dosing diffusion cell. The relationship between physicochemical properties of the drugs studied and their percutaneous penetration was studied. Purity for the compounds studied ranged from 99.09% to 100% in which 99.89% purity was obtained for diclofenac base. At 7.4, the % ionized of piroxicam was found to be 95.12%, while for other drugs were in the range of 98.01% and 99.96%. The true partition coefficient values in the n-octanol/water system are in the range of 1.85 and 2.85, while in the n-octanol/phosphate system ranged from 2.14 to 3.70. Observed solubility in water, phosphate buffer and n-octanol ranged from 0.033 to 0.322, 0.202 to 0.329 mg per ml, and 2.19 to 16.10 mg per ml, respectively. A linear relationship was found between water solubility and melting point between steady-state rates of permeation across intact and viable skin, between n-octanol solubility and maximum predicted flux and between molecular volume and the ratio of maximum predicted flux. Predicted flux calculated was compared with the experimental data which resulted in a high correlation. Physicochemical criteria which were determined the feasibility of non-steroidal anti-inflammatory drugs studied for transdermal delivery were identified. The relationships obtained in this study provide an essential physical and chemical properties that govern transport of non-steroidal anti-inflammatory drugs across hairless mouse skin.

Ethanol and hexane extracts of the leaves and male flowers of Luffa cylindrica were evaluated for antiemetic and anti-inflammatory effects using chick emesis model and carrageenan-induced rat paw oedema. The antiemetic effect was observed at 150 mg/kg body weight, whereas the anti-inflammatory effect was observed at doses of 500,750 and 1000 mg/kg body weight orally. Chlorpromazine 150 mg/kg and indomethacin 10mg/kg orally were used as standard antiemetic and anti-inflammatory drugs. The antiemetic effect was determined by calculating the mean decrease in the number of retching compared to the control group after 10 minutes of copper sulfate (50 mg/kg orally) administration. The degree of paw oedema of all the groups was measured using a plethysmometer at the 5th hour of carrageenan (1% w/v) administration. All extracts except hexane extract of leaves exhibited statistically significant (P<0.001) antiemetic and except hexane extract of flower, all extracts exhibited statistically significant (P<0.05) anti-inflammatory effects.
In this article, we form the exact wave solutions of the Jimbo-Miwa equation and the Calogero-Bogoyavlenskii-Schiff equation by applying the new generalized (G'/G)-expansion method. We explained the new generalized (G'/G)-expansion method to look for more general traveling wave solutions of the above mentioned equations. The traveling wave solutions attained by this method are in terms of hyperbolic, trigonometric and rational functions. The graphical representation of the obtained solutions is kink soliton, singular kink soliton, singular soliton and singular periodic solution. This method is very significant for extracting exact solutions of NLEEs which habitually occur in mathematical physics, engineering sciences and applied mathematics.
The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best-performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 Englishto-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.0 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.
Background: Uterine leiomyoma is the most common benign smooth muscle tumor of unknown aetiology. Progesterone may contribute to leiomyoma growth through the induction of B-cell lymphoma-2 (BCL-2) protein in leiomyoma cells. This study aims to determine the patterns of Bcell lymphoma-2 (BCL-2) and progesterone receptor (PR) expression in uterine leiomyomas seen at LTH, Ogbomoso, over a five-year period using immunohistochemical techniques.Methods: This was a hospital-based retrospective study of histologically diagnosed leiomyomas in the histopathology department of a teaching hospital between January 2012 and December 2016. A total of 141 cases of uterine leiomyomas were semi-quantitatively analysed immunohistochemically for PR and BCL-2 antigens. Results: Immunohistochemical analysis showed that out of 141 cases studied, 74 (52.5%) and 118 (83.7%) were positive for BCL-2 and PR, respectively. Among the 141 cases, 23 (16.3%) were negative for both PR and BCL-2. There was a moderate positive correlation between the immunohistochemical expression of BCL-2 and PR antigens, with a p-value < 0.001 (Pearson correlation = 0.563). Conclusion: This study showed that the majority of women with leiomyomas expressed both progesterone receptor and B-cell lymphoma-2 antigens. Therefore, selective women with leiomyomas could benefit from progesterone receptor modulators instead of undergoing invasive procedures such as myomectomy or hysterectomy.
Social competence is often seen as a desirable trait during adolescence as it is considered as a protective factor in resilient individuals. It promotes personal and interpersonal effectiveness by enhancing skills needed for dealing with environmental challenges in daily life situations. Poor social competence has been associated with a number of psychosocial troubles during adolescence, including mental disorders, emotional and behavioral problems. Of the many skill building programs used to enhance adolescent social competence, Life Skills Education and Training have been significant ones. The present study investigates the utility of life skills training in enhancing social competency during adolescence. A pre- and post-test experimental design was used in the study to analyze the stated objectives. Adolescent Social Competency Scale was used to select the study sample. 160 adolescent students (mean age=16.44) who scored low on social competence participated in the study. These were randomly divided into the experimental and control group (n=80), consisting of equal number of male and female adolescents (n=40). Participants in the experimental group were trained on six of the ten core life skills, based on the module prepared by the researcher. The training lasted for 10 sessions following which post-test assessments were done. Data obtained was analyzed using descriptive statistics like mean, standard deviation and inferential statistics including independent sample t-test and repeated measures of ANOVA. The results of the study indicate a significant effect of life skills training in enhancing adolescent social competence, irrespective of gender.
The current study seeks to develop and validate a high-performance liquid chromatography method for atorvastatin diastereomer separation and analysis. In particular, we wish to identify the many diastereomers in atorvastatin, which can help us to better understand their pharmacological properties and provide significant information for pharmaceutical applications. Atorvastatin was chromatographed on a Chiralcel® OD-RH column and n-hexan-2-propanol (95:05 v/v) as the mobile phase, with an injection volume of 10 µL. The solution was pumped at a continuous flow rate of 1 mL/min, with a detection wavelength of 260 nm. The investigation found two peaks with retention times of 3.23 and 3.85 min, respectively. The resolution, capacity, and selectivity factors obtained were Rs = 1.2, k′1 = 3.50, k′2 = 4.37, and α = 1.24.

The current study was designed to explore the analgesic effects of methanol extracts from the leaves of Samanea saman Merr. and Prosopis cineraria Druce., using tail immersion test. Thermal stimuli produced painful reactions in mice by dipping the tail tips of the mice into hot water. Methanol extracts of the leaves of Samanea saman Merr. and Prosopis cineraria Druce. were administered intraperitoneally at the dose of 100mg /kg body weight. Pethidine 50mg/Kg intraperitoneally was used as a standard analgesic drug. The tail-flick latency delay was measured at 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 hours after the intraperitoneal administration. Both extracts produce analgesic effects when compared with pethidine.
The recent boom in Android mobile device usage has caused a shift in the information technology and has affected the way how information and data are stored, shared among the mobile users. The advent of social networking applications also demands the availability of resources that can be shared among the authentic users. This paper reviews and compares the available techniques and solutions for detecting Unexpected Permission Authorization to Mobile Apps. It is observed that malware for the android system is also growing significantly, current solutions for detecting malware on smartphones are still ineffective.
Lexical and structural levels of language abound ambiguities that are good source of humor. Consequently, violations of the maxims of conversation are leeway to induce humor in any type of discourse. Adding these two precepts and considering pragmatics as its foundation became the bases in analysing the top-grossing films of Vice Ganda. It sought to identify the verbal linguistic jokes and ambiguities present in the top-grossing films of Vice Ganda; determine on how these ambiguities create devaluation of Grice’s maxims of conversation; and determine on how the ambiguities in verbal linguistic jokes and devaluation of Grice’s maxims of conversation were used as ingredients in Vice Ganda’s top-grossing films. Discourse analysis was used in the study and the analytical framework to induce humor by Taghiyev (2018) was used in analysing the corpora. A priori coding was used to identify the recurring ambiguities and devaluation of maxims in the films. Findings show that lexical-semantic and structural-syntactic ambiguities were present in the films. It was intentionally used in order to create humorous effect in the dialogues of the films. Moreover, the devaluation of the maxims of conversation quietly and unostentatiously, opting out, coping with a clash between maxims, and flouting was deemed an effective ingredient to make the films become comical and appealing to the audience.
Anti-emetic activity Of four aromatic medicinal plants (Curcuma caesia Roxb., Piper longum Linn., Piper nigrum Linn., and Syzygiunt aromaticum (Linn.) Merr. & Perry) was studied in chicks. The ethanol extracts of these plants were administered at 150 mg/kg BW orally. All the extracts showed a significant (P < 0.05) decrease in retches induced by copper sulphate pentahydrate given orally at 50 mg /kg BW. Domperidone was given at 100 mg/kg as a reference drug.
