Benzilic acid: a monoclinic polymorph.

The title compound, CHO, is an α-hy-droxy-carb-oxy-lic acid whose ortho-rhom-bic polymorph has been reported earlier [Qiu (2007 ▸). , , 1819-1824]. The asymmetric unit contains two complete mol-ecules.

Tri-phenyl-phospho-nium tri-chlorido-(tri-phenyl-phosphane-κ)cobaltate(II) benzene disolvate.

The solvated title compound, (CHP)[CoCl(CHP)]·2CH, is the tri-phenyl-phospho-nium salt of an anionic Co chlorido coordination compound; the asymmetric unit features an ion-pair and two benzene solvent molecules. One of the solvent mol-ecules shows rotational disorder. C-H⋯Cl and P-H⋯Cl contacts connect the individual constituents into infinite chains extending parallel to [010].

Tris(4-chloro-phen-yl) phosphate.

The title compound, CHClOP, is the symmetric phosphate derived from -chloro-phenol and phospho-ric acid. Two of the three aromatic moieties adopt -orientation towards the P=O bond while the last chloro-phenol ring is pointing away from this bond. In the extended structure, C-H⋯O bonds connect the individual mol-ecules into sheets lying perpendicular to the crystallographic axis.

Alternative splicing regulation in plants by SP7-like effectors from symbiotic arbuscular mycorrhizal fungi.

Most plants in natural ecosystems associate with arbuscular mycorrhizal (AM) fungi to survive soil nutrient limitations. To engage in symbiosis, AM fungi secrete effector molecules that, similar to pathogenic effectors, reprogram plant cells. Here we show that the Glomeromycotina-specific SP7 effector family impacts on the alternative splicing program of their hosts.

Novel pathogenic variants in HR underlie atrichia with papular lesions in a cohort of 10 families.

Atrichia with papular lesions (APL) is a hair abnormality characterized by loss of hair on the scalp and rest of the body. In a few cases, hair loss is accompanied by the appearance of keratotic papules on the body. It is inherited in an autosomal recessive manner.

The Alopecia Areata Severity and Morbidity Index (ASAMI) Study: Results From a Global Expert Consensus Exercise on Determinants of Alopecia Areata Severity.

Importance: Current measures of alopecia areata (AA) severity, such as the Severity of Alopecia Tool score, do not adequately capture overall disease impact.

Objective: To explore factors associated with AA severity beyond scalp hair loss, and to support the development of the Alopecia Areata Severity and Morbidity Index (ASAMI).

Evidence Review: A total of 74 hair and scalp disorder specialists from multiple continents were invited to participate in an eDelphi project consisting of 3 survey rounds.

-Hy-droxy-isovaleric acid.

The title compound (systematic name: -2-hydroxy-3-methylbutanoic acid), CHO, is the constitutional isomer of α-hy-droxy-butanoic acid. In the crystal, hydrogen bonds involving the alcoholic hydroxyl group give rise to centrosymmetric dimers that are extended to sheets perpendicular to the crystallographic axis.

[1,1'-Bi-cyclo-hexa-ne]-1,1'-diol.

The title compound, CHO, is a symmetric diol derived from the pinacol coupling of cyclo-hexa-none. The asymmetric unit contains three complete mol-ecules. The cyclo-hexane moieties adopt chair conformations.

Uncombable hair syndrome is a rare hair shaft anomaly presenting in childhood with blond, frizzy, and unruly hair. This case report presents a 9-year-old boy with remarkable hair where the mother, after reading a medical paper on hair shaft anomalies, suspected uncombable hair syndrome. She reached out to the author group, and the employment of molecular genetics later confirmed the diagnosis of uncombable hair syndrome.

Short anagen hair syndrome: association with mono- and biallelic variants in WNT10A and a genetic overlap with male pattern hair loss.

Background: Short anagen hair (SAH) is a rare paediatric hair disorder characterized by a short anagen phase, an inability to grow long scalp hair and a negative psychological impact. The genetic basis of SAH is currently unknown.

Objectives: To perform molecular genetic investigations in 48 individuals with a clinical phenotype suggestive of SAH to identify, if any, the genetic basis of this condition.

Recent advances in the genetics of alopecia areata.

Alopecia areata (AA) is a common autoimmune-mediated hair loss disorder in humans with an estimated lifetime risk of approximately 2 %. Episodes of hair loss usually begin with isolated hairless patches that may progress to complete hair loss over the entire body. A familial occurrence of AA is well established, with recurrence risks of about 6-8 % in first-degree relatives.

Identification of a novel sporadic U2HR pathogenic variant in a patient with Marie Unna hereditary hypotrichosis.

Marie Unna hereditary hypotrichosis (MUHH) is a rare autosomal dominant hair loss disorder characterized by coarse, wiry, and twisted hair developing during early childhood, and followed by progressive hair loss with puberty. We report a sporadic case of a 4-year-old boy with clinical features suggestive of MUHH, in whom we identified the new pathogenic variant c.67C>T; p.
