This open access book looks at the dramatic history of ovariotomy, an operation to remove ovarian tumours first practiced in the early nineteenth century. Bold and daring, surgeons who performed it claimed to be initiating a new era of surgery by opening the abdomen. Ovariotomy soon occupied a complex position within medicine and society, as an operation which symbolised surgical progress, while also remaining at the boundaries of ethical acceptability. This book traces the operation's innovation, from its roots in eighteenth-century pathology, through the denouncement of those who performed it as 'belly-rippers', to its rapid uptake in the 1880s, when ovariotomists were accused of over-operating. Throughout the century, the operation was never a hair's breadth from controversy.

In early 1953, Rapoport was one of a group of physicians arrested and accused of plotting to kill prominent Soviet citizens. Upon the death of Stalin, all were released and fully rehabilitated. The incident has often been interpreted as an initial stage in a series of purges that would have improved Stalin's control. Rapoport's personal account affords testimony to the anti-Jewish character of the intrigue, to the suspicion and paranoia it engendered within Soviet medical research and practice during this era, and to the author's own strength and courage. It provides added background and detail to the final chapter of Stalin's rule. For scholars and larger research collections.

<p>The objective of this study was to evaluate the intake, performance parameters, digestibility of dry matter, and nutrients in diets with increasing levels of metabolizable energy containing protected fat, as well as the economic analysis of the diets of ½ Boer x ½ Saanen goat kids finished in a feedlot. Twenty-eight uncastrated male goat kids with an initial weight of 19.02 ± 2.20 kg and an age of 88 ± 5.77 days were used and assigned to a completely randomized design in four diets: a control with 2.5 Mcal ME/kg DM and the others with 2.6, 2.7, and 2.8 Mcal ME/kg DM with protected fat (Lactoplus®). The animals were kept on experiment until they reached approximately 32 kg of weight. In order to estimate digestibility, we used ADFi as an internal marker. There were treatment effects on the intake of dry matter, organic matter, ether extract, and non-fiber carbohydrates. We observed a quadratic effect of diets on daily weight gain and feed conversion. The diets had no effect on the digestibility of dry matter, organic matter, neutral detergent fiber, or gross energy. The digestibility of non-fiber carbohydrates and total carbohydrates showed a linear decrease, and crude protein increased linearly. We observed a quadratic behavior in ether extract digestibility resulting from the inclusion of protected fat in the diets. The serum cholesterol level was influenced by the diets and showed a linear increase. The economic evaluation was favorable, with a larger net revenue value for the diet with 2.5 Mcal ME/kg DM. The increase of energy density of diet for ½ Boer x ½ Saanen goat kid through the inclusion of protected fat influences negatively the intake of dry matter and the digestibility of non-fiber carbohydrates and total carbohydrates without improving the growth performance of the animals.</p>

This article belongs to the Special Issue Dietary Patterns, Dietary Indices for Colorectal Cancer, Mortality and the Related Disease. ; Nowadays, obesity and its associated metabolic disorders, including diabetes, metabolic syndrome, cardiovascular disease, or cancer, continue to be a health epidemic in westernized societies, and there is an increased necessity to explore anti-obesity therapies including pharmaceutical and nutraceutical compounds. Considerable attention has been placed on the identification of bioactive compounds from natural sources to manage the metabolic stress associated with obesity. In a previous work, we have demonstrated that a CO2 supercritical fluid extract from yarrow (Yarrow SFE), downregulates the expression of the lipogenic master regulator SREBF1 and its downstream molecular targets FASN and SCD in a tumoral context. Since obesity and diabetes are strongly considered high-risk factors for cancer development, herein, we aimed to investigate the potential therapeutic role of Yarrow SFE in the metabolic stress induced after a high-fat diet in mice. For this purpose, 32 C57BL/6 mice were distributed in four groups according to their diets: standard diet (SD); SD supplemented with Yarrow SFE (SD + Yarrow); high-fat diet (HFD); and HFD supplemented with Yarrow SFE (HFD + Yarrow). Fasting glycemia, insulin levels, homeostasis model assessment for insulin resistance (HOMA-IR), lipid profile, gene expression, and lipid content of liver and adipose tissues were analyzed after three months of treatment. Results indicate improved fasting glucose levels in plasma, enhanced insulin sensitivity, and diminished hypercholesterolemia in the HFD + Yarrow group compared to the HFD group. Mechanistically, Yarrow SFE protects liver from steatosis after the HFD challenge by augmenting the adipose tissue buffering capacity of the circulating plasma glucose. ; This work was supported by the Spanish Ministry of Science (Plan Nacional I + D + i AGL2016-76736-C3), Regional Government of Community of Madrid (P2013/ABI-2728, ALIBIRD-CM; P2018/BAA-4343-ALIBIRD2020-CM), the Ramón Areces Foundation, and the EU Structural Funds. ; Peer reviewed

The low-carb high fat (LCHF) diet, a buzz diet in Sweden, is stirring dogmatic conflict between dieters and representatives from the National Food Agency (NFA), even gaining international reputation. After gathering materials from social media and press reports covering the popular diet, a thematic analysis has been conducted. The aim of this study was to investigate how three non-conventional experts and influential promoters of the LCHF movement transact their criticisms of current nutrition authorities, and how they utilize social media for their purpose. The diet has been highly politicized, creating distrust against the established scientific community. Findings indicate that events on the national level led to an increased public awareness of the LCHF diet, providing the supporters with invaluable opportunities to criticize the established nutritional community. This enabled certain prominent advocates of the diet to gain momentum while using features of social media to further the diet's believability.

Nonalcoholic fatty liver diseases (NAFLD) is characterized by accumulation of lipid droplets in the liver. The objective of this study was to evaluate protective effects of fermented Cordyceps militaris extract by Pediococcus pentosaceus ON188 (ONE) against hepatosteatosis and obesity in mice fed a high-fat diet (HFD). Eight-week-old male C57BL/6J mice were fed HFD mixed with ONE for four weeks and its effects on hepatosteatosis and obesity were examined. Although ONE did not change food intake, it reduced body weights of mice at administration dose of 200 mg/kg/day. Activities of lactate dehydrogenase (LDH), aspartate transaminase (AST), and alanine transaminase (ALT) as plasma parameters were reduced by ONE in a dose-dependent manner. Hepatic lipid droplets and triglyceride (TG) levels were also reduced by ONE due to upregulation of fatty acid oxidizing genes such as carnithine palmitoyltransferase (CPT1) and peroxisomal proliferator activated receptor α(PPARα) mediated by induction of sphingosine kinase 2 (SPHK2). In epididymal fat tissue, sizes of adipocytes were significantly reduced by ONE in a dose-dependent manner. This is mainly due to suppression of lipogenesis and upregulation of adipocyte browning genes. Collectively, these results suggest that fermented ONE can activate fatty acid oxidation via SPHK2 in the liver. It can also suppress lipogenesis and activate browning in adipose tissue. Thus, ONE might have potential to be used for the development of functional foods against liver dysfunction and obesity.

This article belongs to the Special Issue Gut Microbiota and Immunity. ; Alcohol binge drinking (BD) and poor nutritional habits are two frequent behaviors among many adolescents that alter gut microbiota in a pro-inflammatory direction. Dysbiotic changes in the gut microbiome are observed after alcohol and high-fat diet (HFD) consumption, even before obesity onset. In this study, we investigate the neuroinflammatory response of adolescent BD when combined with a continuous or intermittent HFD and its effects on adult ethanol consumption by using a self-administration (SA) paradigm in mice. The inflammatory biomarkers IL-6 and CX3CL1 were measured in the striatum 24 h after BD, 3 weeks later and after the ethanol (EtOH) SA. Adolescent BD increased alcohol consumption in the oral SA and caused a greater motivation to seek the substance. Likewise, mice with intermittent access to HFD exhibited higher EtOH consumption, while the opposite effect was found in mice with continuous HFD access. Biochemical analyses showed that after BD and three weeks later, striatal levels of IL-6 and CX3CL1 were increased. In addition, in saline-treated mice, CX3CL1 was increased after continuous access to HFD. After oral SA procedure, striatal IL-6 was increased only in animals exposed to BD and HFD. In addition, striatal CX3CL1 levels were increased in all BD- and HFD-exposed groups. Overall, our findings show that adolescent BD and intermittent HFD increase adult alcohol intake and point to neuroinflammation as an important mechanism modulating this interaction. ; This research was funded by Spanish Ministry of Health, Social Affairs and Equality, Government Delegation for the National Drugs Plan (2018/013 to MRA and PNSD 2016I016 to JMa); Generalitat Valenciana, Conselleria de Educación, Dirección General de Universidades, Grupos de Investigación de excelencia, PROMETEOII/2018/132 to JMi; Ministerio de Economía y Competitividad' (FIS, PI14/00438) to JMa.

This paper explores the problem of knowledge and knowledge making among Polish primary care doctors. Following Kirsten Hastrup and Tim Ingold, I argue that doctors are skilful social-weavers capable of exploring and reconciling various orders of knowledge. Thus, through a diverse set of knowledgeable yarns – originating from professional and state regimes, and embedded in today's social relationships and economies – doctors are involved in the art of weaving a fabric composed of many, it would seem, contradictory orders of knowledge. The fabric in question is one in a constant state of reworking – although it is one that establishes a meaningful and knowledgeable environment in which the doctors can perform.
