Purpose: The classification of impacted maxillary third molars (IMTMs) facilitates interdisciplinary communication and helps estimate the degree of surgical difficulty. Thus, this study aimed to develop a 3-dimensional classification of the position and depth of impaction of IMTMs and to estimate their prevalence with respect to gender and age. Materials and Methods: This cross-sectional retrospective study analyzed images in sagittal and coronal conebeam computed tomography (CBCT) sections of 300 maxillary third molars. The proposed classification was based on 3 criteria: buccolingual position (buccal, lingual, or central), mesial-distal position (mesioangular, vertical, or distoangular), and depth of impaction (low, medium, or high). CBCT images of IMTMs were classified, and the associations of the classifications with gender and age were examined using analysis of variance with the Scheffé post-hoc test. To determine the associations among the 3 classifications, the chi-square test was used (P<.05). Results: No significant association of the classifications with gender was observed. Age showed a significant relationship with depth of impaction (P=.0001) and mesial-distal position (P=.005). The most common positions were buccal (n=222), vertical (n=184), and low (n=124). Significant associations among the 3 tested classifications were observed. Conclusion: CBCT enabled the evaluation of IMTMs in a 3-dimensional format, and we developed a proposal for a new classification of the position and depth of impaction of IMTMs.

In this study, volumetric oxygen mass transfer coefficient (kLa) was selected as a criterion for facilitatingthe scale up of xylitol production by Candida guilliermondii at the bench and pilot-scale level. A kLa valueof 16 h 1 was applied in reactors with volumetric capacity of 2.4 L, 18 L and 125 L. Fermentation wassuccessfully scaled-up from the bench to pilot-scale level with all experiments demonstrating aminimum of 60% xylose to xylitol conversion efficiency. Under all evaluated conditions glycerol andethanol were also produced as by-products of xylose metabolism. Only minor differences were observedin the fermentation profile when reactor volumes ranging from 2.4 L to 125 L were used forexperimentation purposes, reaching, at pilot scale, yield and volumetric productivity of 0.55 g g 1and 0.31 g L 1 h 1, respectively, with maximum specific growth rate of 0.26 h 1. This demonstrates andreinforces the feasibility of using kLa as scale up criterion. The use of this parameter allowed precisereproduction of results obtained at bench bioreactor level to a larger scale; this is extremely crucial andimportant information considering that the aim of the proposed biotechnological process is to reach thelevel required for the industrial viability.

The components of the endogenous cannabinoid system are widely expressed in the gastrointestinal tract contributing to local homeostasis. In general, cannabinoids exert inhibitory actions in the gastrointestinal tract, inducing anti-inflammatory, antiemetic, antisecretory, and antiproliferative effects. Therefore, cannabinoids are interesting pharmacological compounds for the treatment of several acute intestinal disorders, such as dysmotility, emesis, and abdominal pain. Likewise, the role of cannabinoids in the treatment of chronic intestinal diseases, such as irritable bowel syndrome and inflammatory bowel disease, is also under investigation. Patients with chronic intestinal inflammatory diseases present impaired quality of life, and mental health issues are commonly associated with long-term chronic diseases. The complex pathophysiology of these diseases contributes to difficulties in diagnosis and, therefore, in the choice of a satisfactory treatment. Thus, this article reviews the involvement of the cannabinoid system in chronic inflammatory diseases that affect the gastrointestinal tract and highlights possible therapeutic approaches related to the use of cannabinoids.

(Background and purpose) In response to the challenges posed by population growth, a new category of residential space, known as micro-apartments, has recently emerged. Efficient space utilization in these micro-housing environments has become a critical consideration. In recent times, transformable furniture has gained significance as an essential element for enhancing the quality of life in these spaces and maximizing available space. However, research on transformable furniture is still limited. Therefore, this study aims to provide practical suggestions for the future use of transformable furniture in micro-apartments through a comprehensive literature review and case analysis of transformable furniture within this context. (Method) To categorize adaptable furniture types in micro-apartments, our research initiated a conceptual understanding of the definition of furniture, proceeded to a thorough historical review of transformable furniture, and explored classification mechanisms through an extensive literature review. Additionally, a comprehensive case study analysis was conducted in order to comprehend the utilization of transformable furniture, drawing from reputable publications of the last five years. Consequently, our research facilitated the classification of transformable furniture into vertical and horizontal transformations, aligning with prior studies that categorized spatial elements using these parameters. Further differentiation was achieved by examining specific mechanisms, notably, sliding and folding. Following this classification, an in-depth analysis was conducted to assess the functional aspects related to human behavior both before and after furniture transformation. (Results) The analysis produced several noteworthy findings. Firstly, it became evident that the primary function of most transformable furniture is ease of storage when not in use. Secondly, horizontal transformable furniture aimed to extend the horizontal plane, facilitating various activities such as eating and working. Lastly, vertical transformable furniture was primarily designed to provide comfort for relaxation, ultimately enhancing the overall quality of life. These insights underscore the multifaceted role of transformable furniture in micro-apartments. (Conclusion) This study has revealed that transformable furniture is actively employed to maximize space efficiency in micro-apartments. Notably, transformable furniture in micro-apartments places significant emphasis on easy storage as an integral space-saving feature when not in use. Additionally, the expansion of horizontal plane utilization is crucial within micro-apartments to facilitate various human activities, including eating and working. Lastly, vertical transformable furniture, which undergoes a transition from hidden vertical spatial elements into horizontal plane furniture, significantly contributes to an improvement in the quality of life by accommodating activities such as sleep and relaxation, which are fundamental to residential spaces. These discoveries emphasize the vital role of transformable furniture in augmenting the functionality and comfort of micro-apartments.

Since the 1990s, the Tanzanian public housing authority, the National Housing Corporation (NHC), has been changing its goal, from prioritizing delivery of affordable housing, to becoming a leading commercial and residential real estate developer. This happens against a backdrop of market-based reform and the state’s growing reliance on private markets to support urban development. In this paper, we look at the impact of NHC’s new approach and its effect on housing production and every day practice in Dar es Salaam. The analysis is based on a case study of two new NHC middle to high-income development projects and housing practice in the neighbourhoods surrounding these projects. Analysis is informed by semi-structured interviews, and project and site investigation. Findings indicate that currently, NHC operates like a private corporation, prioritizing market-rate developments over low-income housing projects, and promoting segregated developments based on land value criteria, while also lacking protocols regarding its trickling down approach. High input costs and declining state subsidies are some of the factors mentioned as a challenge towards meeting the housing needs of moderate to low-income households. The paper contributes to the international debate concerning the state’s adoption of business-like approaches to housing production and the affordability crisis.

Heart pain is the most frequent complaint leading patients to seek medical help. Functional heart symptoms, especially chest pain, are prevalent and, according to the International Classification of Diseases (ICD-10), are described as “somatoform autonomous functional disorders of the cardiovascular system.” The problem lies in the fact that pain does not always have a somatic background, that is, it may be related to crucial underlying heart disease. The population does not know how to differentiate somatic pain from significant ischemic symptoms, and based on the patient's complaints, traditional medicine ends up treating other underlying cardiac diseases. Many unsuccessful unconventional therapies have been proposed in recent years, including herbal medicines that seek to disrupt the disease's pathogenesis. The present review summarizes research carried out in the last 5 years on natural products' heart complaints, including myocardial ischemia, arrhythmia, and heart failure. Several herbal medicines may be used as a replacement or complementary treatment strategy. A total of 17 medicinal plants have shown promising results in preclinical studies. However, human clinical trials are scarce; only two have been presented. Generally, the data are bland, and many issues have been raised about herbal therapies' safety, efficacy, and mode of action. Besides, relevant clinical trials, future perspectives, and possible clinical applications are discussed.

The simultaneous saccharification and fermentation (SSF) process is a promising strategy to obtain ethanol from cellulosic biomass. In this study, sugarcane bagasse was supplemented with ricotta whey to increase the sugar, vitamin, and trace metal concentrations in the fermentation medium. The optimum conditions for SSF ethanol production from a mixture of sugarcane bagasse and ricotta whey produced by Kluyveromyces marxianus CCT 7735 were evaluated considering five factors: cellulase concentration, cellulosic biomass concentration, pH, temperature, and agitation. The highest ethanol yield was 49.65 g/L with a cellulosic biomass of 80 g/L, pH value of 5.05, agitation at 65 rpm and temperature of 39.2ºC. The results demonstrated that a mixture of the cellulosic residue of sugarcane bagasse and ricotta whey is promising for ethanol production because the ethanol yield in the mixture was higher than that in single substrate of sugarcane bagasse.
