“…Although a slight predilection for males had been noted in the developed clime, recent studies done locally showed a slight female preponderance, similar to reports about 3 decades ago [18][19][20][21]. Lipomas are usually asymptomatic in nature.…”

Background: A lipoma is one of the commonest benign tumors in surgical practice. Lipomas are usually found on the trunk and limbs but less commonly within the abdomen, where they occur frequently in the mesentery as well as the subserosa and submucous layer of the gastrointestinal tract. Pre-peritoneal lipomas are rare. Case Presentation: A 44-year-old woman presented with a painless and progressive right-sided abdominal swelling of 5 months duration. Examination revealed a 16cm x 14cm slightly mobile and non-tender firm-to-hard hour-glass-shaped mass extending from the right hypochondrial to right iliac and the suprapubic regions. Abdominal ultrasonography showed a 5cm x 6cm bowel thickening in the right iliac fossa suggestive of an ileocecal mass while a computerized tomography showed a 20.8cm x 6.3cm x 20.1cm hypodense mass within the peritoneal cavity, extending from the epigastric region to the pelvis, anterior to the bowel loops and more to the right. At laparotomy, a huge, well encapsulated yellowish mass in the pre-peritoneal space, weighing 1,520g was excised. Histology confirmed a lipoma. Conclusion: A preperitoneal lipoma is an uncommon soft tissue tumor and the giant ones are extremely rare. Although a rare cause of a painless abdominal swelling, pre-peritoneal lipoma should be considered as a differential diagnosis in patients presenting with an unremarkable feature suggestive of an intra-abdominal pathology.

“…Lipomas are benign tumors of adipose tissue and represent one of the most common soft tissue neoplasms of mesenchymal origin [8,9]. Lipomas can be solitary, multiple generalized lipomatosis and multiple symmetric, usually slowly growing, diffused or encapsulated, can vary in size and shape and show great heterogeneity in cell populations presented within the tissue [10,11].…”

“…The occurrence of lipomas in all body parts has been reported, mostly in subcutaneous depots but also in other tissues, organs and body cavities. Both male and female can be affected and all ages although they usually appear in the middle age [9,12]. Several studies reported that lipoma tissue is a good source of stem cells that might be used for regenerative medicine purposes, naming lipoma “useless tissue useful in the application of regenerative medicine and tissue engineering” [13].…”

Lipomas are benign adipose tissue tumors of unknown etiology, which can vary in size, number, body localization and cell populations within the tissue. Lipoma-derived stem cells (LDSCs) are proposed as a potential tool in regenerative medicine and tissue engineering due to their similar characteristics with adipose-derived stem cells (ADSCs) reported so far. Our study is among the first giving detailed insights into the molecular signature and differences in the differentiation capacity of LDSCs in vitro compared to ADSCs. Mesenchymal stem cell phenotype was analyzed by gene expression and flow cytometric analysis of stem cell markers. Adipogenesis and osteogenesis were analyzed by microscopic analysis, cytochemical and immunocytochemical staining, gene and protein expression analyses. We showed that both LDSCs and ADSCs were mesenchymal stem cells with similar phenotype and stemness state but different molecular basis for potential differentiation. Adipogenesis-related genes expression pattern and presence of more mature adipocytes in ADSCs than in LDSCs after 21 days of adipogenic differentiation, indicated that differentiation capacity of LDSCs was significantly lower compared to ADSCs. Analysis of osteogenesis-related markers after 16 days of osteogenic differentiation revealed that both types of cells had characteristic osteoblast-like phenotype, but were at different stages of osteogenesis. Differences observed between LDSCs and ADSCs are probably due to the distinct molecular signature and their commitment in the tissue that governs their different capacity and fate during adipogenic and osteogenic induction in vitro despite their similar mesenchymal phenotype.

“…The study agrees with Koech, et al (2015) that majority of the students make use of a library in the University of Eldoret, Kenya. On the contrary, patronage has been reportedly low in some studies (Odu, 2017;Mohammed, Abduallahi & Abubakar, 2017). Odu (2017) also reported a decline in library patronage while Mohammed, Abduallahi & Abubakar.…”

“…Despite the value of university libraries' resources to learning, several studies have reported low patronage of university libraries by students. The studies of Mohammed, Abduallahi and Abubakar (2017), Odu (2017) and Abdulsalami and Efosa (2020) captured the declining patronage in the academic library even with the provision of digital resources and services. This continual decline may be as a result of inadequate information resources to satisfy the users' information need.…”

Library patronage is a measure of user satisfaction. The study examined library patronage of undergraduates in private universities in Lagos State, Nigeria. The study employed survey design and questionnaire was used for the data collection. The population of the study comprised 5,616 undergraduates. Three hundred and sixty-five (365) respondents were sampled based on Research Advisor’s Table for determining sample size. The collected data was analyzed using descriptive and inferential statistics. The findings revealed that undergraduates in private universities often patronized the university libraries in Lagos State, Nigeria. Subject specific materials (x̅= 2.52) were mostly consulted, followed by project and dissertations (x̅=2.44) and reference materials (x̅=2.18). The finding also revealed that resource availability had a significant influence on library patronage of undergraduates (R2= 0.073, t(300) = 4.873, p < 0.05). The study recommended that the library management should take proactive measures to improve library resources underutilized by the students under study. Keywords: Library patronage, private university, resource availability, undergraduates.
