Establishing intraspecific breeding and hybridization programs and determining genetic variability are two important issues for aquaculture. However, interspecific hybridization to improve growth and feeding efficiency is limited. For this purpose, the embryonic and larval development of reciprocal crosses of Clarias gariepinus (Burchell, 1822) and Clarias jaensis (Boulenger, 1909) were studied under laboratory conditions. The fertilization rate varied from 63.33% to 92%, while the hatching rate ranged from 55.68% to 76% with the highest value in hybrids ♀Cg × ♂Cj. Crosses between ♀Cj × ♂Cj, ♀Cg × ♂Cj and ♀Cj × ♂Cg had embryonic stages similar to those of the pure sib ♀Cg x ♂Cg. all crosses, however, had different timing for the various embryological stages. Hatching occurred at 32 h 15 min and 38 h for ♀Cj × ♂Cj and ♀Cj × ♂Cg, and 23 h and 23 h 30 min, respectively, for ♀Cg × ♂Cg and ♀Cg × ♂Cj. However, both crosses produced viable larvae until the first external feeding. The external morphological features of the larvae were completely formed by the 10th day after hatching. The body forms of the crosses at this time were indistinguishable from the pure sib. This study thus laid the groundwork for further comparative studies on hybrid performance and characterization.

In young patients, even small circular facial defects after the excision of benign skin tumors present a reconstructive challenge. The usefulness of a V-Y advancement flap for reconstructing such defects is well documented. We refined this technique as a mini V-Y advancement flap consisting of two subcutaneous pedicles that vascularize the skin island via subdermal plexus lateral bridges. This technique was used for 21 middle-aged or younger patients with a small benign skin lesion. None of them experienced any postoperative complications. Aesthetically excellent results were found in all patients. This small advancement flap could be attempted as an alternative to fusiform excision of small skin lesions, particularly in younger patients.

The characterization of African bonytongue Heterotis niloticus fish farming was conducted in the Bi-modal agro-ecological zone of Cameroon from January to May 2021, Thirty-two fish farmers were interviewed and SPSS 6.2 Version was used to analyse the data. The results showed that the majority of fish farmers (81%) are men above 51 years, all of whom are Christians with more than fifty percent of them married. About 43% of them have university level education, and more than 6% of them considered the farming of Heterotis niloticus as their main income-earning activity. The main objective of Heterotis niloticus farming is sales (50%) and the uses (56%) of waged labour. A majority of the farmers produced reared African bonytongue in a polyculture system and 65% of them raised Heterotis niloticus in derivation ponds.

Introduction: Several studies have suggested that decreased FEV1 is associated with cardiovascular risk in COPD patients. Objective: To identify the prevalence of undiagnosed peripheral artery disease (PAD) and the relationship between leg atherosclerosis and clinical indices, which predict COPD mortality in Japanese COPD patients. Methods: We performed a cross-sectional study in 51 COPD patients and 51 age-matched, healthy control smokers. We measured ankle-brachial index (ABI) as a marker of atherosclerosis of the legs, pulmonary function, body mass index, modified Medical Research Council (MMRC) dyspnea scale, and smoking pack-years. We also calculated the ADO index (Age, Dyspnea, and Obstruction), an established predictor of mortality in COPD patients. Co-morbidities including diabetes mellitus, hypertension, and hypercholesterolemia were identified from blood laboratory tests and medical records. Results: Five subjects (9.8%) had an ABI 0.9. ABI was significantly lower in the COPD patients than in the healthy control smokers (p 0.05). The prevalence of PAD was marginally higher in COPD patients than in control smokers (p = 0.09), with the prevalence of ABI 1.0 being significantly higher in COPD patients than in control smokers (p = 0.04). In the COPD patients, ABI showed significant correlations with age (p = 0.006), FEV1 (p = 0.004), smoking pack-years (p = 0.047), MMRC dyspnea scale (p = 0.0005), SaO2 (p = 0.001), andADOindex (p 0.001). Multiple linear regression modeling showed the factors associated independently with ABI were age, FEV1, smoking pack-years, MMRC dyspnea scale, and SaO2. Conclusion: The risk of leg atherosclerosis in Japanese COPD patients is higher than in smokers without COPD. Leg atherosclerosis in COPD patients is associated with clinical indices that predict COPD mortality.

The study aimed at analyzing the most important factors affecting the retail marketing of honey in Saudi Arabia. Cross sectional survey was employed using field interview (direct contact) with a random sample of 343 retail outlets represented all its forms and patterns in seven major cities in Saudi Arabia. Measurements like market share, Gini coefficient and Herfindahl Hirschman Index (HHI) were used to estimate the indicators of market structure and its performance. The result showed that the structure of honey retail market is generally closer to pure competition with a small concentration in some areas. Gini coefficients of concentration, as well as the values of the Herfindahl Hirschman Index (HHI) were relatively low for retailers. The average marketing margin was about SAR 6.4/Kg for local honey while the marketing margin of imported honey was about SAR 113/Kg. The high profit margin variation between local and imported honey is due to the high marketing costs, lower supplied quantity and higher demand for local honey. The estimated cost of marketing of onekilogram of honey was about 8 SAR at the retail level. From retailers’ point of view, low quality, lack of marketing services, improper display, high rental property, lack of knowledge and experience of the consumer about properties and quality characteristics honey, high prices and shortage of some varieties of honey in some specific season are the most important problems of honey marketing in the Saudi market. Setting priorities between different brands of honey plays a noticeable role in marketing. Some honey producers and traders were very concerned about unfair competition of honey market through high promotion as a brand based on their long history in the production and supply of high-quality varieties of honey from specific and well-known varieties. Hence, intensive awareness creation effort through training, exhibition, media and advertisement are required to improve the perception of consumers towa
