Visible-light photocatalysis is a rapidly developing and powerful strategy to initiate organic transformations as it closely adheres to the tenants of green and sustainable chemistry. Generally, most visible-light-induced photochemical reactions occur through single-electron transfer (SET) pathways. Recently, visible-light-induced energy transfer (EnT) reactions have received considerable attentions from the synthetic community as this strategy provides a distinct reaction pathway, and remarkable achievements have been made in this field...

Background and Aims: Pregnancy guidelines for women with Inflammatory Bowel Disease (IBD) provide recommendations regarding anti-TNF cessation during pregnancy, in order to limit fetal exposure. Although infliximab (IFX) leads to higher anti-TNF concentrations in cord blood than adalimumab (ADA), recommendations are similar. We aimed to demonstrate the effect of anti-TNF cessation during pregnancy on fetal exposure, for IFX and ADA separately. Methods: We conducted a prospective single center cohort study...

The correct diagnosis of CPA tumours is a relatively common issue in both neurological and ENT practice, the omission of which can have serious consequences for the patient. Properly set clinical guidelines and diagnostic protocols are key aspects of good clinical practice. In the case of CPA tumours, two options are available: the first is diagnosis with the help of an ABR as the primary tool for determining the group of patients with a possible tumour; the second is an MRI scan of the posterior cranial fossa...

INTRODUCTION: Imaging studies have hystorically been used to support the clinical otorhinolaryngological evaluation of the upper respiratory tract for the diagnosis of obstructive causes of oral breathing. OBJECTIVE: The objective of this study was to compare 3D volumetric measurements of nasal cavity, nasopharynx and oropharynx of obstructed mouth-breathing children with measurements of non-obstructed mouth-breathing children. METHODS: This retrospective study included 25 mouth-breathing children aged 5-9 years evaluated by otorhinolaryngological clinical examination, flexible nasoendoscopy and full-head multi-slice computed tomography...

Thirteen new ent-kaurane diterpenoids, stigmaydenes A-M (1-13), together with two known compounds (14, 15), were isolated from the crude extract of corn silk ( Zea mays). The structures of the compounds were confirmed by comprehensive spectroscopic analyses. The absolute configuration of compound 1 was defined by single-crystal X-ray diffraction. The absolute configurations of the compounds were also confirmed by comparison of experimental and calculated specific rotations. The compounds were evaluated for their neuroprotective effects against H2 O2 -induced SH-SY5Y cell injury, and compound 8 was active at 100 μM, as determined by flow cytometry (annexin V-FITC/PI staining) and Hoechst 33258 staining...

OBJECTIVES: To assess the effect of near-peer head and neck anatomy teaching on undergraduates and to quantify the benefit from a focussed teaching course. Near-peer teaching involves colleagues within close seniority and age proximity teaching one another on a specified topic. DESIGN: Small group teaching sessions were delivered to medical students on 3 key areas of ENT anatomy. Participants were given a precourse and postcourse questionnaire to determine the benefit attained from the course...

Aconitum carmichaelii has long been used as a traditional Chinese medicine, and its processed lateral roots are known commonly as fuzi. Aconitine-type C19 -diterpenoid alkaloids accumulating in the lateral roots are some of the main toxicants of this species, yet their biosynthesis remains largely unresolved. As a first step towards understanding the biosynthesis of aconitine-type C19 -diterpenoid alkaloids, we performed de novo transcriptome assembly and analysis of rootstocks and leaf tissues of Aconitum carmichaelii by next-generation sequencing...

1.The Individual Funding Request (IFR) process was introduced by Clinical Commissioning Groups to regulate Procedures of Limited Clinical Value 2.In the South Buckinghamshire region, this affects common ENT procedures including adenotonsillectomy and grommet insertion 3.Only 3 of 118 applications for grommet insertion were rejected and the majority (23/27) of tonsillectomy rejections were due to insufficient supporting evidence from the patients' GPs 4.Despite the majority of applications eventually being accepted, the process has undoubtedly delayed treatment for our patients; impacting 18 week target times 5...

The chemical constituents from the n-butanol fraction of the 70% ethanol extract of Datura metel roots were separated by silica gel and ODS chromatogram columns as well as preparative HPLC. On the basis of spectral data analysis, their structures were elucidated. Twenty-one compounds were obtained and their structures were identified as citroside A (1), coniferin (2), paeoniflorin (3), (6R,7E,9R)-9-hydroxy-4,7-megastigmadien-3-one 9-O-[α-L-arabin-opyranosyl-(l→6)-β-D-glucopyranoside] (4), (1R,7R,10R,11R)-12-hydroxyl anhuienosol (5), kaurane acid glycoside A (6), ent-2-oxo-15,16-dihydroxypimar-8(14)-en-16-O-β-glucopyranoside (7), ginsenoside Rg₁(8), ginsenoside Re (9), notoginsenosides R₁(10), N-butyl-O-β-D-fructofuranoside (11), salidroside (12), hexyl β-sophoroside (13), 2,6-dimethoxy-4-hydroxyphenol 1-glucoside (14), benzyl-O-β-D-xylopyranoxyl(1→6)-β-D-glucopyranoside (15), (Z)-3-hexenyl-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (16), N-[2-(3,4-dihydro-xyphenyl)-2-hydroxyethyl]-3-(4-methoxyphenyl) prop-2-enamide (17), cannabisin D (18), cannabisin E (19), melongenamide B (20), paprazine (21)...

Historically, ENT has been a very competitive surgical specialty. In recent years, the number of applicants to higher surgical ENT training has been in decline. This is not surprising, given that the proportion of foundation doctors directly entering specialty training has fallen from 71.3% in 2011 to 42.6% in 2017. If this continues, there is a real possibility of under-filling training posts, which would be a setback to the British Association of Otorhinolaryngologists (ENT-UK) recommendation for an expansion of the specialist workforce...

Introduction: The field of otolaryngology has become the leading specialty in the management of head and neck pathology and trauma. Graduate medical education programs tasked to train military head and neck surgeons within the Department of Defense (DoD) maintain certification by ensuring adequate surgical case volume and training. In recent years, surgical case numbers have declined due to an overall healthy active duty patient population and deployments of residency faculty. As such, a novel initiative between the San Antonio Military Medical Center and the South Texas Veteran's Healthcare system was developed to provide seamless care among active duty service members, dependents, retirees, and veterans...

Activated racemic 2,3-disubstituted 1-indanones 1 possessing two stereolabile centers were stereoselectively reduced to the corresponding chiral 2,3-disubstituted-1-indanols 2 by ruthenium(II)-catalyzed dynamic kinetic resolution-asymmetric transfer hydrogenation. In particular, this route offers a practical access to a new class of conformationally rigid enantiopure 1,4-diols 2k-m having four contiguous chiral centers. Transformation of ent-2k into a Pallidol analogue via a highly diastereo- and regioselective Friedel-Crafts benzylation of o-chloroanisole is presented...

BACKGROUND: Acute otitis media (AOM) is one of the most common childhood illnesses. While many children experience sporadic AOM episodes, an important group suffer from recurrent AOM (rAOM), defined as three or more episodes in six months, or four or more in one year. In this subset of children AOM poses a true burden through frequent episodes of ear pain, general illness, sleepless nights and time lost from nursery or school. Grommets, also called ventilation or tympanostomy tubes, can be offered for rAOM...

The stem bark extract of Suregada zanzibariensis afforded a previously undescribed ent-abietane diterpenoid trivially named mangiolide (1) and a known jolkinolide B (2) via anticancer bioassay-guided fractionation. The CH2 Cl2 :MeOH extract of S. zanzibariensis was initially analysed for its anticancer properties against three cancer cell lines, renal (TK10), melanoma (UACC62), and breast (MCF7) and was found to be potent at low μg/mL ranges. Compound 1, 6α-acetoxy-14-keto-ent-abieta-7(8),13(15)-diene-16,12-olide (mangiolide) inhibited the growth of renal (TK10) with a GI50 of 0...
