Published: April 2023

Di era yang semakin berkembang, tuntutan akan kualitas sumber daya manusia dalam dunia kerja telah meningkat sehingga beberapa mahasiswa mengantisipasi hal tersebut dengan mengikuti program internship atau magang sambil berkuliah. Ketika mahasiswa mengikuti program internship, maka kesibukkan mereka juga turut meningkat karena tuntutan tidak hanya datang dari bangku perkuliahan saja, tapi juga terhadap tugas magang. Akhirnya kegiatan menunda-nunda pengerjaan tugas kuliah atau prokrastinasi akademik menjadi hal yang tidak terelakkan. Salah satu langkah yang dapat dilakukan ialah dengan mengidentifikasi tingkat self-regulated learning mahasiswa atau kemampuan mengatur diri dalam memperoleh pengetahuan serta keterampilan. Berdasarkan hal tersebut, maka penelitian ini bertujuan untuk mengetahui hubungan self-regulated learning dan prokrastinasi akademik pada mahasiswa yang mengikuti program internship. Metode yang digunakan adalah kuantitatif untuk mengetahui hubungan antara dua variabel yang terlibat. Hasil penelitian menunjukkan bahwa mahasiswa cenderung cukup sering melakukan prokrastinasi akademik dengan perolehan aspek kognisi 81,7% serta motivasi 71%. Oleh karena itu, peneliti selanjutnya dapat mengembangkan variabel lain untuk mengetahui faktor lain yang dapat mempengaruhi prokrastinasi akademik serta meningkatkan sebaran jumlah responden.

Bacterial blight caused by Xanthomonas axonopodis pv. punicae (Xap) is a major biotic diseases in pomegranate (Punica granatum L.). In the field survey which lasted 2 year in six different geographical locations, Xap strains from the severely infected plant material collected including DuhokCcenter, around Erbil, Zaxo, south of Duhok, Akre, and Amedi. Xanthomonas was detected from infected plant material and its identity was confirmed by morphological, Microbial and Molecular Characterization. To study its genetic variability and phylogenetic relationship two important loci were targeted namely ITS region of 16s rDNA, 16S rRNA and then a PCR-RFLP was performed for PCR product of 16s rRNA loci using Hinf I, Hae III, and Rsa I restriction enzymes. The PCR-RFLP showed the genetic similarity coefficient ranging from 1.00 to 3.73, and the dendrogram grouped all tested strains in 4 clusters. The result revealed that this disease is in blooming stage in the country which was thought that has not been recorded before in pomegranate. To the best of our knowledge this is the first record of Xap. In Kurdistan/ Iraq therefore, further studies are needed to be performed to manage this hazardous bacterium.

This study was aimed to determine the prevalence of ESBLs in E. coli and their relation to plasmid profiling patterns in a sample of patients in Iraqi hospitals. The total number of E. coli isolates 91 (49%) were collected out of 185 clinical samples. The antibiotic sensitivity test for isolates showed high resistance percentage to Nitrofurantion 95.7%, amoxicillin and Ceftriaxone to each of which 91.3% and to Ceftazidime 90.2%, while the highest sensitivity was observed against Imipenem 100%, Meropenem 99% then to Amikacin 93.5%. The Multi drug resistant (MDR) isolates were 53(58.2) % and ESBLs producers were 45 (49.5) %. Plasmid profile analysis showed nineteen different plasmid profile patterns were obtained based on molecular weight and number of plasmids content. Most β-lactamase producers had multiple plasmids, where’s single plasmid profile predominant in non-β-lactamase-producing isolates. The presence of common plasmid among the isolates increases the distribution of resistant plasmid in the community. In conclusion, ESBLs producing bacteria can transferred between species by plasmids leading to cross resistance which give a limited options for treatment.
BIOINFORMATICS EVALUATION OF CRISP2 GENE SNPs AND THEIR IMPACTS ON PROTEIN
Authors: Zaid A. Hussein  , Abdulkareem A. Al-Kazaz
Published: April 2023

This study evaluated the CRISP2 gene's functional single nucleotide polymorphisms, and its results may be advantageous for future population-based studies and early diagnostic discoveries, particularly in developing effective treatments. The CRISP2 gene encodes a secretory protein with a high cysteine content, which belongs to the family of cysteine-rich secretory proteins (CRISP). SNPs are genetic variations that may affect a protein's structure or functionality. Prior to carrying out a broader population investigation, it is possible to evaluate suspected functional SNPs since it is challenging to uncover functional SNPs in disease-linked genes. As a result, using various bioinformatic prediction models, the potentially harmful three SNPs of the CRISP2 gene were predicted in this in-silico study from the neutral ones. Out of a pool of 260 nsSNPs, three SNPs (L56V, M176I, and C196R) been selected to anticipate their impacts on functions and structures along with their capability to impair protein stability. Actually, two of the three SNPs in the CRISP2 gene L56V and C196R were identified as possibly detrimental, although M176I was not. But all of these SNPs dropped significantly protein stability, per the I-Mutant suite.

Published: April 2023

This study was designed to investigate the influence of pre-estrus (PE) synchronization and post-mating (PM) vitamins AD3E treatment on the reproductive performance of Awassi ewes raised at four Iraqi provinces. Seventy six Awassi ewes were randomly divided within each province into two groups. The first group (n=15, except for Karbala, n= 11) were im injected with five AD3E injections (150 IU / dose), biweekly interval. The 1st injection was 1.5 months PM, while the 2nd and 3rd injections were at the time of progestagen-impregnated vaginal sponges insertion. The 4th injection was at the time of the vaginal sponge’s removal, whereas the 5th injection was 14 days PM. The control group (n=5) was intramuscularly injected with 5 ml normal saline at similar periods. The AD3E groups exhibited higher (P≤0.01) fertility and conception rates as compared to the control groups in Al-Najaf and Karbala provinces. Higher (P≤0.01) lambing rate and liter size were noticed in AD3E groups than those of the control group for all provinces. In conclusion, pre-estrus synchronization and post-mating vitamin AD3E treatment improved the reproductive performance of Awassi ewes.

Authors: Omar Mardenli  , Ali A. Ibrahim  , Ali S. A. Al- Tawash
Published: April 2023

Two experiments were conducted to study the efficiency of the ovine follicular fluid (OFF) and the age of ewe on in vitro nuclear maturation of Awassi sheep oocytes (Experiment 1) and the subsequent stages of early embryos and their quality (Experiment 2). The OFF has been added to the basic maturation medium (TCM-199) with three different levels (A: 0% (Control group), B:15%, C:25% and D:50%) while the ages of the ewes were determined into two main groups (> 2 and 1-2 year). In the first experiment, across the two age groups, matured oocytes in C solution achieved the highest (p=0.006) rates of metaphase-II (85.70 and 82.35 % respectively). In the second experiment, oocytes belonging to > 2 and 1-2-year ewe age groups (C Solution) achieved the highest (p=0.001) rates  of fertilization (23.17 and 30.73% respectively). Similar trend applies to the cleavage stage, the rates reached 35.14 and 41.27% respectively (p=0.01). No significant differences were noticed at the different stages of cleavage (2-4 cell, morula, and blastocyst). The resulting embryos of B (> 2-year ewe age group) and C solution (1-2-year age group) achieved the highest (p=0.04) rates of Type1 embryos (69.56 and 76.92% respectively). A significant difference was noticed in type2 embryos (p=0.02), embryos of the first and second age groups (Solution D) achieved the highest rates (46.15 and 33.33% respectively). It can be concluded that the adding of 25% OFF to the maturation media led to significant improvement in the rates of maturation, cleavage and type1 embryos of sheep oocytes.

Published: April 2023

This study was performed to determine whether active optical sensors could develop an algorithm for N recommendation for the potato crop (Solanum tuberosum L.). The experiment was conducted in Maine State, (USA) during the growing season of 2018-2019. Six N rates (0-280 kg ha-1) were applied on eleven locations under a randomized complete block design (RCBD), with four replications. Data of normalized difference vegetation index-(NDVI) were collected via active sensors, GreenSeeker-(GS), and Crop Circle-(CC). Sensors measurements collected at the 20th of the leaf stage were significantly associated with tuber yield, where the exponential model exhibited a better fit for the regression curve. Conventionally, 168 kg N ha-1 produced the maximum potato yield. The N rate computed based on in-season sensors reading reduced by about 12-14% from the total N rate that growers use to apply based on the conventional approach. Studying potato cultivars separately in the same soil properties can improve the algorithm accurately.

Inferring the Migration of Services in Pervasive Edge Applications
Authors: Boulougaris Georgios , Kolomvatsos Kostas
Published: April 2023

The coexistence of the Internet of Things (IoT) and Edge Computing (EC) aims to offer a processing infrastructure close to end users that will improve the performance of applications and limit the latency in the provision of services. Services are adopted to assist in the execution of tasks imposed by the needs and requests of end users or applications. The definition of an effective framework for services management in the distributed edge nodes is a necessary condition to achieve the aforementioned goals. This is because services should be placed at the appropriate locations in order to meet the challenges defined by the demand for them. The discussed framework ought to address the trade-off between overheads related to services migration/replication and data transmission in order to deliver the most efficient setup for edge nodes. In this paper, we propose a proactive statistical model that creates a ‘map’ for allocating the available services upon the observed demand and supports edge nodes to decide when and where it is necessary to migrate/replicate a sub-set of services. Our aim is to place services at locations where an increased demand imposed by the requested processing activities, however, under the uncertainty about the future evolution of the requests. We elaborate on the evaluation of the proposed model and offer a comparative assessment with relevant schemes adopting real datasets. Our experimental evaluation demonstrates that our approach reinforces the heterogeneous engaged edge nodes to correctly infer the time instance and the location when/where services should be migrated/replicated to meet the dynamics of their demand. The interesting is that the proposed model achieves encouraging outcomes when it is adopted to cope with the mobility of end users.

Published: April 2023

This is a pseudo-label refinement method for unsupervised Person ReID. The method select cluster sample that is most similar in a cluster to represent the cluster, and reassign pseudo-labels for those not most familiar with their corresponding cluster sample. Comprehensive experiments demonstrate that our method not only improves the external validity metric scores of the pseudo-labels, effectively narrowing the gap between pseudo-labels and the true distribution, and minimizing the accumulation of noisy label errors, but also significantly improves the performance of IICS on three public datasets – Market-1501, DukeMTMC-ReID, and MSMT17.  Our baseline method is IICS, and it may also improve other baseline such as PPLR. Future works will focus on the adaptive to all other baselines.

Published: April 2023

This study assessed the effects of self-efficacy on the academic achievement of biology students in secondary schools in Delta State. The study population comprised all biology students in public senior secondary schools in Delta State. The sample was 245 biology students drawn from six (6) schools using stratified random sampling technique. The pre-test post-test control group quasi-experimental design was used in this study. Biology Achievement Test (BAT) and self-efficacy questionnaire were used as instruments for data gathering. The data collected were analysed using the mean, standard deviation, and t-test. Findings revealed that, although there is a significant difference between the post-test scores of biology students taught with the self-efficacy strategy and those taught with the lecture method, there is no significant difference between the post-test scores of male and female biology students taught with the self-efficacy strategy. The study concludes that self-efficacy is a major variable that affects the academic achievement of biology students in secondary schools in Delta State. The study recommends that the government, through the Ministry of Education, train teachers to acquire self-efficacy skills to help them teach more effectively, efficiently, and make the teaching-learning process more meaningful in order to improve the academic achievement of biology students, boost students’ confidence in their ability to perform a task efficaciously, and not give up while facing difficulties.

Authors: Ajah Austin A. , Egbono Frank F.
Published: April 2023

Flavonoids has been shown to have anti-inflammatory and anti-oxidant properties, which may have potential protective effects against mechanical induced models of pain. In this context, administering methanolic extract of artocarpus altilis (MEAA) during the experimental rats could potentially increase the pain threshold, which could in turn, increase the quality of health and life expectancy. Dearth literature exists on the analgesic effects of Bread fruit on pain. Hence, this study aims at investigating the potential anti-nociceptive properties of MEAA to increase paw withdrawal latency using murine model. 25 Wistar rats were randomly selected into five groups: Group 1=(control); Group 2, 3 & 4 (100, 200, 300-mg/kg MEAA, respectively) and Group 5=100-mg/kg Aspirin (ASP). The rats were subjected to mechanical pain-behavioral studies at 30, 60, 10 and 120 minutes after administration of test substances. Results obtained showed that, at 30 minutes post administration of MEAA and ASP, significant increase (p<0.05) in pain threshold was observed in 100, 200, 300-mg/kg and ASP groups when compared to control. At 60 minutes, significant increase (p<0.05) in pain threshold was observed in 200, 300-mg/kg and ASP groups when compared to control. Finally, at 90- and 120-minutes, significant increase (p<0.05) in pain threshold was observed in 300-mg/kg group only, when compared to control. In conclusion, graded doses of MEAA showed analgesic properties by increasing pain threshold when administered 30, 60, 90 and 120 minutes prior to subjection of the animals to mechanical pain. Therefore, MEAA have shown analgesic properties that could even be more effective than the reference drug (aspirin).
Tricyclic Terpane Fingerprint of Crude Oils from Niger Delta, Nigeria
Authors: Onyema Mark Obinna , Eselemondi John Tamaralayefa
Published: April 2023

Tricyclic terpanes identified in two representative crude oils from the Central and Western Niger Delta (oil- RVAG and oil-DTIR, respectively) ranged from C19 to C29, including C24 tetracyclic terpane. Plot of the abundances of tricyclic terpanes show similarity in the distribution profile of the oil samples, characterized by the uncommon distribution of C20 and C21 tricyclic terpanes indicating both Niger Delta crude oils are derived from similar source organic matter. Ratios of C22/C21 and C24/C23 tricyclic terpanes indicate source rocks of the crude oil samples were deposited in a deltaic environment and derived from mixed marine/terrestrial organic matter. Additional, C26/C25 tricyclic terpanes, C24 tetracyclic/C23 tricyclic terpanes and C24 tetracyclic/C26 tricyclic terpanes indicate the crude oil samples are generated from shale source rocks derived from terrestrial organic matter, with oil-DTIR receiving a more terrestrial contribution, and marine facies, with oil-RVAG receiving a more marine contribution. Thermal maturity, determined from ratios of low to high molecular weight tricyclic terpanes, indicate the crude oil samples are mature with oil-RVAG more mature than oil-DTIR. The ratios of C19/C23 and C20/C23 tricyclic terpanes, which indicate high maturity of the crude oils, suggested terrestrial and marine source for oil-RVAG and oil-DTIR, respectively, contrasting with the relative abundances of tricyclic and tetracyclic terpanes. This implies the abundances of C19 and C20 tricyclic terpanes, particularly in crude oils at high maturity, as in the Niger Delta, has interfering effect on source interpretation and its ratios be used in combination with other parameters for evaluating Niger Delta crude oils.

Published: April 2023

The Institute for Immediate Decisions (UitVoerbaar Bij Voorraad) currently does not prioritize human rights and equal protection before the law, because the regulations regarding the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) are uncertain in their application. The purpose of this study is to find and analyze the Civil Case Execution Regulations regarding the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) which currently have not been able to realize Pancasila justice; Weaknesses of the Civil Case Execution Regulations regarding the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) in Indonesia at this time; and Reconstructing Civil Case Execution Regulations for the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) based on the Pancasila Value of Justice. In this study, the constructivism paradigm was used, the socio-legal research approach method. The data sources in this study consist of primary data sources and secondary data sources consisting of primary legal materials, secondary legal materials and tertiary legal materials. Related to qualitative descriptive data analysis. Legal theory as an analysis of Grand Theory (Pancasila justice theory), Middle Theory (legal system theory), Aplaid Theory (Progressive Law). The findings of the study are that (1) the Civil Case Execution Regulation on the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) based on the Value of Justice has not been able to realize Pancasila Justice, because it does not prioritize human rights and legal certainty as characteristics of Pancasila justice. Apart from that, it appears that unequal treatment before the law, because of the regulations as stipulated in article 180 paragraph (1) HIR / article 191 paragraph (1) RBG, there must be Authentic Evidence of the Plaintiff, so the Immediate Application of the Decision cannot be dropped if each - each party has authentic evidence. (2) Weaknesses in the Civil Case Execution Regulations regarding the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad). In substance, this regulation is still floating (floating norm) so that the Immediate Decision cannot be implemented and executed (non-executable). This is what causes the legal structure, namely the Court does not comply with the Application of the Immediate Decision (Uitvoerbaar Bij Voorraad). This fact can become a legal culture that is not good, both within the judiciary itself and among justice seekers and society. (3) Reconstruction of Civil Case Execution Regulations on the Implementation of Immediate Decisions (UitVoerbaar Bij Voorraad) based on the Value of Justice by Removing Article 180 paragraph (1) HIR / Article 191 paragraph (1) RBG, to realize Pancasila justice which prioritizes human rights and equality before the law.

Marriage dispensation is the granting of permission to marry against deviations from the minimum age permitted in the marriage law. Marriage dispensation can be requested from the court with urgent reasons and must be married immediately. This urgent reason has caused debate, because based on the determination of the religious court as a whole it grants or gives dispensation approval to prospective brides who are pregnant or have committed acts prohibited by religious law and decency. While reasons other than that can be rejected by the judge. The purpose of this research is to analyze and find the reconstruction of the regulation of marriage dispensation in the perspective of human rights based on the value of justice. This study uses the Postpositivism paradigm, with an empirical juridical approach that uses primary data. Methods of data collection using interviews, observation, and field systems. The legal theory used in this dissertation is the theory of justice as the Grand Theory, the middle theory of the legal system theory and the Applaid theory of the theory of benefit. The results of this dissertation research found that the regulation of marriage dispensation in the perspective of human rights has not had the value of justice, namely the current marriage dispensation system based on Law Number 16 of 2019 has not fulfilled a sense of justice related to equal rights before the law and Article 28 B of the Law -The 1945 Constitution of the Republic of Indonesia, it can be seen that dispensation is only given to prospective brides who are pregnant. The current weaknesses in the regulation of the dispensation of marriage in the perspective of human rights are weaknesses in legal substance, legal structure and legal culture. The weakness of the marriage dispensation system is that it does not provide a clear understanding of the urgent reasons, causing debate regarding the urgent reasons and giving rise to the interpretation that the urgent reason is that the candidate is pregnant and results in differences of opinion from the judges. Reconstruction of the regulation on the dispensation of marriage in the perspective of human rights based on the value of justice, namely by reconstructing the provisions in Article 7 paragraph (2) of Law Number 16 of 2019, namely that it is necessary to change the sentence or phrase "reasons are very urgent" and amended with the phrase "which based on the interests of the candidate.

This article analyzes the structuring of Construction Law in Middle Eastern countries. It is an excursus that deals specifically with what the Muqawala contract is, its usefulness and also its history, up to an indication of the most important issues and elements of construction contracts in Middle Eastern countries. Specifically, the most important and legally interesting case relating to the resolution of disputes related to incorrect contractual execution was also analysed. In addition, a further analysis was carried out on Arbitration as one of the most common instrument and also the most common form of dispute resolution in contracts involving international Parties and related to the same on a number of increasingly widespread and increasingly used local arbitration bodies including the Dubai International Arbitration Center and DIFC/LCIA Arbitration Centre.
The Verb Phrase in Shupamem
Authors: Ngoupayou Ernest Njifon
Published: April 2023

This paper analyses the structure of the verb phrase in Shupamem; a Grassfields Eastern Bantu language spoken in the West region of Cameroon. More importantly, this study identifies the different components of the verb phrase in Shupamem in one hand and the order of these various elements in the other hand. I propose that Shupamem is a satellite-framed language; in this language motion events are described by attaching a particular particle to the verb. Most interestingly, it is shown that in Shupamem, the structure of the VP is not rigid. Hence, in this language, the various components of the VP that is the adjective, the adverb, the preposition and the noun can be freely combined and thus giving us twelve different structures of the VP.

In Nigeria, it is standard practice to discharge petrochemical compounds on sewage degradation in a septic tank, which has led to consistent sewage dislodgement in the septic tank that serves our household. The study was carried out to determine the effect of some petrochemical products, such as petrol, kerosene, and diesel. Some laboratory tests were conducted, which included biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, conductivity, and total coliform count. Under aerobic conditions, the researchers built four different experimental sewage treatment systems in the lab. We used a scale ratio of 2: 1 for the effluent and petrochemical products in order to get a total mixture of 200ml for both since the reagent bottle, we used for the test has a total measurement of 300ml. With respect to the above ratio, 33 mL of effluent and 67 mL of petrochemical products such as petrol, kerosene, and diesel were poured into each of the three samples (i.e., the 300 mL reagent bottle), and the last sample was used as the control. Samples were collected at a weekly interval for a period of four weeks for the laboratory tests. The findings of the tests revealed that there was a slow rise in the BOD and the COD during the second week, but that this rise eventually slowed down and became smaller over the course of time. Weekly, the pH, conductivity, and total coliform count decrease. The abrupt spike in the second for BOD and COD is due to the presence of additional carbon, hydrogen, and oxygen molecules, which eventually decrease with time. This merely indicates that petrochemical products have the potential to be utilised in the reduction of biological oxygen demand (BOD), chemical oxygen demand (COD), and coliform bacteria found in sewage.
Reliability of Soil and Ground Improvement Techniques in Niger Delta Region of Nigeria
Authors: Oluwaseun Mohammed Ganiyu , Dada Irheren
Published: April 2023

This research work presents a study of the reliability of ground improvement methods in three states of the Niger Delta Area of Nigeria namely: Rivers, Bayelsa and Akwa –Ibom states. Natural soil which is peaty clay in nature was obtained from different locations in the area of study and improved with different percentages of chemicals, cement, ranging from 2% to 10% and geotextile materials after which reliability analysis was carried out on them for CBR and UCS tests. Results show that geotextile materials are not suitable for improving the peaty clay soils in the locations under study due to poor values of reliability while the reliability values obtained for soil improved with cement increases with increase in percentage addition of cement and curing period. Reliability values for soil improved with chemicals shows some variability but increase as curing period increases at percentage addition of chemicals from 2% to 6% for Calcium Oxide, Calcium Chloride, Calcium Hydroxide and Aluminium Hydroxide before a decrease in value. Sodium silicate reliability peaked at 8% while the optimal value of reliability for cement was realised at 10%.
A Market Timing Strategy for the GCC Conventional and Shariah Stock Indices
Authors: Prandi Stefano Giovanni , Colecchia Daniele
Published: April 2023

This paper defines and assesses a market timing strategy for the Gulf Cooperation Council (GCC) stock indices, namely the Tadawul All Share Index, FTSE Abu Dhabi General Index, Qatar All Share Index and Qatar Al Rayan Islamic Index. The strategy intends to deliver a consistent reduction in volatility and better risk-adjusted performance. The present empirical study capitalises on the work by Colepand and Copeland (1999) on the US market, re-proposed recently by Bantwa (2020) on the Indian market, which resorts to implied volatility as the trigger to adjust the asset allocation. The strategy hereby proposed is modified considering the higher volatility of the GCC financial markets as well as its preeminent goal – risk-adjusted performance optimisation. Moreover, the implied volatility is unavailable for the GCC stock indices under assessment; therefore, it has been replaced with the forecasted volatility obtained through asymmetric GARCH models (GJR-GARCH), one for each stock index. The active strategy in question is backtested on both the conventional and Islamic stock indices to check whether it overperforms the passive strategy equally well on both types of indices. The empirical findings encourage the adoption of volatility-based market timing models in additional emerging markets and Islamic indices.

The aim was to study the epidemiological, clinical and therapeutic aspects of paraphimosis at the CSRéf of Markala. Patients and Methods: We conducted a prospective and descriptive study of five patients who had consulted for paraphimosis in the operating theatre of the Markala referral health centre from 1er January 2019 to 31 December 2021, i.e. a two-year period. Our study included all patients who consulted for paraphimosis at the CSRéf of Markala with a usable medical file. The criteria for non-inclusion were: Phimosis without other pathologies of the penis. The records were not usable, as this was a prospective study. Results: The frequency of paraphimosis was 2.1% out of 235 patients hospitalized and operated on at the CSRéf of Markala during the study period. Four of our patients had no particular medical or surgical history, but the oldest of our patients had already undergone a hernia repair and an appendectomy at the time ; the average age of our patients was 15.3 years, with extremes ranging from 3 years to 53 years . However, we note that there is no specific age of onset of paraphimosis The treatment received by all our patients was posthectomy. No major complication was noted in our patients, however we deplore a loss of sight in two of our patients for a long term follow-up in order to identify other unknown aspects in the management of paraphimosis. Conclusion: Paraphimosis is a true urological emergency that occurs in uncircumcised men when the foreskin is trapped behind the glans crown, which can lead to long-term strangulation of the glans and compromise its vascularity hence their immediate management paraphimosis.

Published: April 2023

Background: Low back pain and sciatica are two of the most common health disorders that people experience. Both the number of hours that employees put in and the amount of money that is lost by the nation as a whole see significant reductions as a result of these changes. Before beginning any kind of treatment with these individuals, it is very necessary to do a thorough physical assessment on them. It is possible for symptoms to worsen as a result of receiving insufficient medical or surgical treatment, which increases the likelihood of this happening. The purpose of this study is to evaluate the effectiveness of acupuncture in conjunction with PLID treatment. Methods: This inquiry took place at SUOXI Healthcare Limited in Shantinagar, Dhaka, Bangladesh. A 36-year-old male patient has been complaining of lower back discomfort, tingling and numbness of right leg for the last two years. The diagnosis was confirmed with a MRI of lumber spine. Results: Follow-up research showed promising outcomes. He no longer felt discomfort in his lower back and tingling and numbness of right leg, which he had been experiencing for two years. PLID patients may benefit from acupuncture, according to the findings of this study.
