Segregation analysis in the families confirmed 13kb novel homozygous deletion of SRD5A2 in case I and c.586G>A in case II. The present study confirms the diagnostic value of whole exome sequencing in the detection of DSD aetiology, especially when several differential diagnoses are possible.

The increase of longitudinal integrated curricula in medical schools worldwide represents the shift towards an outcome-oriented education. This novel model allows comprehensive student-patient interactions over time and integrates the educational content across disciplines. According to quantitative research, students, patients, doctors and communities benefit from this educational model in terms of participant satisfaction, learning outcomes and clinician recruitment. However, quantitative research does not provide detailed information on programme implementation processes. Therefore, this review aims to summarise facilitators and barriers of programme implementation reported in qualitative and mixed methods studies.

The authors reviewed the literature about facilitators and barriers for the implementation of longitudinal integrated curricula in undergraduate medical education programmes. The systematic search was conducted in MEDLINE, Embase and PsycINFO on 2 December 2019. The authors used the CASP cheommunicate common objectives with all participants. They should clarify the implementation of the objectives in all processes in a transparent and structured manner. Considering reporting guidelines, future studies in this field should document more transparently the methods used to gain qualitative insights and the researchers' personal involvement.

The authors derived practical recommendations for the implementation of undergraduate, patient-centred, integrated medical curricula. Programme managers need to define and communicate common objectives with all participants. They should clarify the implementation of the objectives in all processes in a transparent and structured manner. Considering reporting guidelines, future studies in this field should document more transparently the methods used to gain qualitative insights and the researchers' personal involvement.Dermatologically, FGFR3 mutations can lead to acanthosis nigricans (AN), epidermal nevi, and seborrheic keratosis. A recent case report found that topical rapamycin (sirolimus) can improve FGFR3-induced epidermal nevi with AN features in children, specifically with Fitzpatrick skin type (FST) I/II, and we would like to expand these findings to skin plaques with extensive AN-like features in the FST IV/V adolescent population. An 18-year-old female with FST IV/V and FGFR3-induced hypochondroplasia presented to our clinic with extensive AN-like plaques. Significant improvement with lightening and thinning of the plaques was observed after applying 1% topical rapamycin cream twice daily. Topical rapamycin should be considered as a treatment option for AN, particularly in FST IV/V adolescents with FGFR3-induced AN.Mitochondrial disorders make up a large class of heritable diseases that cause a broad array of different human pathologies. They can affect many different organ systems, or display very specific tissue presentation, and can lead to illness either in childhood or later in life. While the over 1200 genes encoded in the nuclear DNA play an important role in human mitochondrial disease, it has been known for over 30 years that mutations of the mitochondria's own small, multicopy DNA chromosome (mtDNA) can lead to heritable human diseases. Unfortunately, animal mtDNA has resisted transgenic and directed genome editing technologies until quite recently. As such, animal models to aid in our understanding of these diseases, and to explore preclinical therapeutic research have been quite rare. This review will discuss the unusual properties of animal mitochondria that have hindered the generation of animal models. It will also discuss the existing mammalian models of human mtDNA disease, describe the methods employed in their generation, and will discuss recent advances in the targeting of DNA-manipulating enzymes to the mitochondria and how these may be employed to generate new models.Vitamin E (α-tocopherol) is a lipid-soluble essential vitamin recognized for improvement in degenerative health conditions, abating cancer risk, and coronary heart diseases in humans. While in plants, it acts as a free radical scavenger that protects cells against oxidative and photooxidative damages. The daily consumption of potato makes it a key target for biofortification with vitamins for eliminating vitamin deficiency in large populations. Vitamin E biosynthetic pathway genes have been overexpressed in plants via genetic engineering to enhance the α-tocopherol content. Major genes involved in the vitamin E biosynthesis in plants viz. the homogentisate-phytyltransferase (At-HPT) and γ-tocopherol-methyltransferase (At-γ-TMT), isolated from Arabidopsis were constitutively overexpressed in potato (Solanum tuberosum L.). The molecular analyses of independent transgenic lines revealed a stable integration of both the genes in the plant genome. The transgenic potato exhibited significantly improved vitamin E contents up to 173-258% in comparison to the untransformed control plants. Transgenic tissues also exhibited increased cellular antioxidant enzymes, proline, osmolyte, and glutathione content that are directly correlated with the ability of the plant to withstand abiotic stresses imposed by salt (NaCl) and heavy metal (CdCl2 ). Therefore, the current strategy of increasing the vitamin E content in potato with enhanced tolerance to abiotic stresses might greatly aid efforts to engineer crops for human health benefits and greater yield under adverse environmental conditions.Under phosphorus (P) deficiency, Lupinus albus develops cluster roots that allow efficient P acquisition, while L. angustifolius without cluster roots also grows well. Both species are non-mycorrhizal. We quantitatively examined the carbon budgets to investigate the different strategies of these species. Biomass allocation, respiratory rates, protein amounts and carboxylate exudation rates were examined in hydroponically-grown plants treated with low (1 μM; P1) or high (100 μM; P100) P. At P1, L. albus formed cluster roots, and L. angustifolius increased biomass allocation to the roots. The respiratory rates of the roots were faster in L. albus than in L. angustifolius. The protein amounts of the non-phosphorylating alternative oxidase and uncoupling protein were greater in the cluster roots of L. albus at P1 than in the roots at P100, but similar between the P treatments in L. angustifolius roots. click here At P1, L. albus exuded carboxylates at a faster rate than L. angustifolius. The carbon budgets at P1 were surprisingly similar between the two species, which is attributed to the contrasting root growth and development strategies.
