Published: September 2024

Pulmonary tuberculosis poses a diagnostic dilemma to clinicians especially in the absence of typical presentation. The hypersensitivity to tuberculosis infection in other parts of the body can lead to nondestructive, para-infectious arthritis. This is known as Poncet disease, one of the clinical syndromes of musculoskeletal tuberculosis. Herein, we report a case of smear-negative pulmonary tuberculosis presenting with atypical features. It started with multiple joint pain, followed by the presence of multiple tender nodular skin lesions over the bilateral shins and wrist. Subsequent investigations led to the diagnosis of smear-negative pulmonary tuberculosis. Joint pain and erythema nodosum disappeared soon after antituberculosis therapy, supporting the diagnosis of Poncet disease.

African Ethnonyms and Toponyms: An Annotated Bibliography
Authors: Batoma Atoma
Published: September 2024

A major trend in African Studies today consists in using traces of African culture embedded in African names and naming practices to recover or reconstruct African heritage. African names are oral records that can be meticulously processed and analyzed by African and Africana scholars. The emphasis is placed on two categories of names: ethnonyms and toponyms. Ethnonyms are names of people and ethnic groups whereas toponyms are names of places. These two categories of names constitute two important subfields of African onomastics. In addition, they are related in three interesting ways. First, some ethnic groups derive their names from place names and vice versa. Secondly, unlike other types of names such as anthroponyms or personal names, which can easily change or disappear according to the biography of the bearer, toponyms and ethnonyms have a durable life span.Toponyms in particular constitute fixed landmarks whose durability makes them important data for historical research. Thirdly, and more importantly, ethnonyms and toponyms constitute an intricate and semiotic structure, a kind of palimpsest that crystallizes a layer of meanings of community experience. These meanings can be conceived of as approaches or facets of the collective experience of a group. There are at least five facets: the geographical, the historical, the linguistic, the symbolic, and the socio-political facets.
This bibliography contains annotations of sources on ethnonyms and toponyms from the Maghreb region and Sub-Saharan Africa dating from 1930 to the present, regardless of the origin, nationality and race of the authors. The principal criterium for the selection of publications is the geographic location of the ethnic groups they describe or analyze. I have also tried to ensure that all the facets described above are represented in my bibliography. English, French and German have been my three research languages. In some rare cases I have used sources in Portuguese and Afrikaans after having native speakers check my approximative understanding of the texts.
Prosody and Intonation in Non-Bantu Niger-Congo Languages: An Annotated Bibliography
Authors: Green Christopher R.
Published: September 2024

Most linguists are well aware of the fact that data pertaining to languages spoken in Africa are often less readily available than information on languages spoken in Europe and some parts of Asia. This simple fact is one of the first and largest challenges facing Africanist linguists in their pursuit of preliminary data and references on which to base their research. The challenge of locating relevant materials only increases in difficulty as the search for information narrows to include only certain subfields of linguistics or languages of a particular genetic stock. Africanist linguists interested in phonology and phonetics will find that a preliminary search for information and references pertaining to the study of intonation and prosody in African languages yields a significant bias towards materials focusing on languages in the Bantu branch of the Niger-Congo language family, as well as a select few welldocumented languages spoken elsewhere on the continent. One can explain this research bias toward Bantu languages in terms of a number of factors, including the sheer number of constituent languages in this sub-family, the relatively peaceful conditions that exist in many of the nations in which people speak Bantu languages, and overwhelmingly significant factors that have influenced the post-colonial attitudes toward Europeans and Western research in certain parts of the African continent. This bias compounds the research difficulties faced by linguists interested in languages outside the Bantu branch of the Niger-Congo family in that linguists have devoted less time to these languages, and the materials that exist are sometimes difficult to obtain.
This bibliography will provide an account of materials published over the past twenty-five years pertaining to the study of intonation and prosodic phonology and phonetics in non-Bantu Niger-Congo languages. I will assume that the reader has some familiarity with both African languages and linguistics. One will find an explanation of any limits on the scope and selection of materials included in this bibliography in this introduction.

Published: September 2024

The right leadership style can facilitateemployees motivation, inspiration, and persuade them to accomplish their individual and organizational goals with the support of management. Many SMEs in Nigeria do not include their staff in the decision-making process due to a lack of strong leadership abilities, which hinders their capacity to flourish. This study investigated how the leadership styles of SME in Asaba, Delta State impacts the organizational efficiency of those businesses. The study gathered information from SME managers and owners using a cross-sectional survey research methodology. The study found a weak but positive nexus between authoritarian leadership style and performance of SME. The study also discovered that the performance of SMEs in Delta State is significantly impacted by democratic leadership style. As a result, it may be concluded that a democratic leadership style impacted positively on SME performance in Delta State at the rate of 17%. Finally, the study concludes that laissez-faire leadership has the highest positive impact on the performance of SMEs in Delta State. This indicated that laissez-faire leadership had the most significant impact amongst the three leadership styles or philosophies examined. It showed that Delta State's small and medium-sized firms would perform 48% percent better for every 1 percent increase in Laissez-Faire leadership. Therefore, this study recommends that in SME management, a laissez-faire leadership style should be applied in appropriate situations to foster creativity.

Streptozotocin (STZ) is widely used to increase blood glucose levels and generate diabetic animal models. However, the dose of STZ is important as it may lead to inadequate induction of diabetes, metabolic complications, and influence the behavior of animals. Therefore, this study aimed to determine the various impacts of different STZ dosages on the brain cognitive performance associated with hyperglycemia and organ complications of diabetic rats. Animals were divided into three groups: (1) rats received a single dose of STZ (SSTZ; 55mg/kg), (2) rats received multiple doses of STZ (MSTZ; 40mg/kg) and (3) control rats received citrate buffer (CON; 0.2mL/rat) for three consecutive days intraperitoneally. Brain cognitive performance was assessed using the Y-maze test, and blood glucose level was performed weekly. The histopathological study was conducted on the pancreas, liver, kidney, and brain tissues. Results showed that animals with single and multiple doses of STZ decreased the number of entries and time spent in the novel arm of the Y-maze task. Multiple doses of STZ caused severe degenerative changes in the pancreatic islet, brain neuron apoptosis, inflammation in the liver, and tubular cell injuries. Thus, these results indicate that both single and multiple dosages of STZ influenced brain cognitive performance, which was associated with hyperglycemia and tissue degeneration in diabetic animals.

The antinociceptive effect of flower extracts at two doses (100mg/kg and 200mg/kg) wasassessed using an acetic acid-induced writhing and tail immersion pain model.The flower extracts produced significant dose-dependent inhibition of nociceptive behaviour in the acetic acid-induced writhing test.When compared to the vehicle control group, the percentage of writhing inhibition reached around 70.7% and 69.07% in the groups of Hibiscus rosa sinensis and Cosmos sulphureus flower extracts that received the highest dose (200mg/kg). In the tail immersion method, the flower extracts showed a dose-dependent increase in the latency time and significantly (p<0.001) reduced pain as compared with the control group. Thus, flower extracts demonstrated peripheral and central antinociception via opioid receptor activation. The phytochemical analysis of flower extracts revealed that they contained alkaloids, glycosides, flavonoids, carbohydrates, steroids, tannins, and phenolic compounds. In conclusion,the flower extracts possess significant antinociceptive properties that are mediated through central and peripheral pathways.

Enhanced Arrhythmia Detection Using Filtered Data, CNN, Graph Convolutional Networks, and SVM on MIT-BIH and PTB Databases
Authors: Mallikarjunamallu K.
Published: September 2024

Arrhythmia classification and detection are essential for the early diagnosis of heart diseases, but accurately identifying arrhythmias is challenging due to the inherent noise in electrocardiogram (ECG) data. This study presents a novel method for arrhythmia detection that follows a systematic approach. First, ECG data from the MIT-BIH Arrhythmia Database and the PTB Diagnostic Database are preprocessed using three distinct filters: wavelet transform (WT), finite impulse response (FIR), and an innovative infinite impulse response (IIR) filter to remove noise. The filtered data are then processed through a one-dimensional convolutional neural network (1D-CNN) and graph convolutional networks (GCNs) for feature extraction. These features are initially classified using a support vector machine (SVM) into normal and abnormal categories. For further detection, the classified data undergo additional processing through Short-Time Fourier Transform (STFT) for time-frequency analysis, followed by Principal Component Analysis (PCA) for dimensionality reduction. Finally, a Bidirectional Long Short-Term Memory (BiLSTM) network is employed to detect specific arrhythmias within the classified signals. The proposed method is evaluated using the MIT-BIH and PTB datasets, demonstrating that the combination of STFT, PCA, and BiLSTM significantly enhances the detection of specific arrhythmias. The inclusion of GCNs and the innovative IIR filter further improves classification accuracy. This approach's effectiveness is validated through comparisons with existing arrhythmia identification methods, highlighting its advancements in both classification and detailed arrhythmia detection.

Published: September 2024

The literature regarding surgical repair of urethral prolapse in dogs is limited and associated with a high recurrence rate. We hypothesized that combined resection and anastomosis (R&A) with urethropexy would be associated with less recurrence of urethral prolapse compared with R&A alone. Medical records of dogs managed surgically for urethral prolapse were reviewed (2013–2023) from three tertiary care hospitals. Inclusion criteria included complete medical records, including surgery reports, short-term postoperative complications, and longer-term follow-up. Forty-six male dogs successfully met the inclusion criteria (16 castrated; 30 intact). Brachycephalic breeds were overrepresented (37/46, 80%). Surgical repair by R&A alone (n = 27), urethropexy alone (n = 6), or a combined R&A and urethropexy (n = 13) was performed. Recurrence rates for these techniques were 13/27 (48%), 2/6 (33%), and 1/13 (8%), respectively. The recurrence rate of urethral prolapse treated by a combined R&A and urethropexy was significantly lower (P < .05) than R&A alone, despite more dogs being overweight and less surgeon experience (each P < .05). Interestingly, dogs neutered before initial diagnosis may be more likely to have postoperative recurrence. Considering general anesthesia risks, an initial combination procedure for urethral prolapse may help prevent recurrence.

Published: September 2024

This study was conducted to test the compressive strength of concrete hollow blocks (CHBs) prepared from four treatments, with 0%, 1%, 2%, and 3% proportion of upcycled plastics as partial replacement to choker aggregates, find out which proportion is the most acceptable in terms of compressive strength, and ascertain the economic cost of CHBs for each proportion. Randomized Complete Block Design (RCBD) was utilized where the four proportions with upcycled plastics were replicated three times and cured in 28 days. The Universal Testing Machine (UTM) was utilized to test the CHBs compressive strength. Results showed that the control treatment had comparable features with the other treatments. It got the highest mean unit weight and compressive strength while Treatment C had the lowest in both aspects. Since the minimum standard compressive strength for CHBs is 1.50 MPa, the control and all treatments passed the standard compressive strength. However, the control treatment was the most acceptable of the four proportions having the highest compressive strength. As to cost, the CHBs prepared with 0% upcycled plastics had the lowest price, with Treatment C getting the highest expense value. With these findings, it can be deduced that the properties of CHBs are affected by the different proportions of aggregates used as mixture substitutes.

Visual survey of colonies of hibernating bats is a traditional research method. The data obtained using this method serve as a basis for determining population trends. These data are especially important for protected areas that ensure the protection and conservation of species and their key habitats. The Ivankivtsi adits (IVK-mines) are located in the territory of the Podilski Tovtry National Nature Park (in the protected zone of the national park). The site is a system of adits and mines used for machine mining of sawn limestone. This area is also part of the European Emerald Network. The IVK-mines are listed as a key underground site for the conservation of European bat species. The monitoring of wintering bat communities at the IVK-mines has continued for about 20 years. Surveys are conducted annually, but mostly only the entrance parts of the adits are covered (about 50% of the site’s total area). Every few years, total bat counts are carried out throughout the entire mine system. The previous total bat count at the IVK-mines was conducted in 2009 (15 years ago). In January 2024, a repeated total survey of bats was conducted. According to its results, 5967 bats belonging to 12 species were recorded. Compared to the previous total count, the increase in numbers is about +60%. The dominant species by number is Barbastella barbastellus. The western barbastelle has been forming a large winter aggregation for 15 years, which in 2024 comprised about 2000 individuals. Other barbastelles are found in smaller groups (10 to 200 individuals) and as single individuals. Studies of winter aggregations of European bats show significant fluctuations in the numbers of bats between surveys of several years, indicating that environmental factors that affect hibernation strategies mask real population trends. In addition, climate change creates opportunities for cold-loving species to hibernate outside of their main roosts, such as in tree hollows, which makes it difficult to understand and interpret bat survey data. This phenomenon is obviously observed in the IVK-mines. Therefore, an important condition for improving the understanding of real trends in the population dynamics of species will be the transition to more modern and high-quality survey and monitoring methods of winter aggregations of bats and their hibernation, particularly via automatic survey systems using light barriers.
