Gynaecological brachytherapy can cause anxiety, distress and discomfort. It is not known how variation in delivery impacts women's experiences. To inform future research an online survey was carried out to identify variations in brachytherapy and support available to women receiving treatment for locally advanced cervical cancer (LACC).

An online survey was sent to 44 UK brachytherapy centres using the Qualtrics® survey platform. It included questions about brachytherapy scheduling, inpatient/day case treatment, anaesthetic/analgesia, non-pharmacological support and health professionals' opinions regarding holistic care. A mixture of closed questions with pre-specified options and open questions were employed. Descriptive statistics were generated to identify variance in UK practice. PP121 Free text responses were analysed using inductive content analysis.

Responses were received from 39/43 eligible centres (91% response rate). Brachytherapy was predominantly given on an inpatient basis at 65% and day case at explore women's experiences with a range of treatment regimes and anaesthesia and analgesia techniques to inform improvements to future clinical care.In the studies on dihydroxy intermediate synthesis, a serendipitous reaction of introducing nitro group from nitromethylene has been observed. Instead of expected dihydroxy compounds, dinitration structures with nitromethylene analogues were prepared under mild conditions by using a metal-free catalyst B(OH)3. In this reaction, the extra nitro group was suggested to be from starting material. Bioassays indicated that compound 3a showed good insecticidal activities against cowpea aphid (Aphis craccivora) and armyworm (Mythimna separata), with LC50 values were 4.9 mg/L and 7.1 mg/L, respectively.Human indoleamine 2,3-dioxygenase 1 (hIDO1) and tryptophan dioxygenase (hTDO) are rate-limiting enzymes in the kynurenine pathway (KP) of l-tryptophan (l-Trp) metabolism and are becoming key drug targets in the combination therapy of checkpoint inhibitors in immunoncology. To discover a selective and potent IDO1 inhibitor, a structure-activity relationship (SAR) study of N-hydroxybenzofuran-5-carboximidamide as a novel scaffold was investigated in a systematic manner. Among the synthesized compounds, the N-3-bromophenyl derivative 19 showed the most potent inhibition, with an IC50 value of 0.44 μM for the enzyme and 1.1 μM in HeLa cells. The molecular modeling of 19 with the X-ray crystal structure of IDO1 indicated that dipole-ionic interactions with heme iron, halogen bonding with Cys129 and the two hydrophobic interactions were important for the high potency of 19.Osthole, a coumarin-type natural product, is isolated from Chinese traditional herbal medicine Cnidium monnieri. In order to improve the pesticidal activity of osthole, and high value-added application of the plant Cnidium monnieri, a series of new derivatives containing hydrazone/acylhydrazone/sulfonylhydrazone skeletons at the C-8 position of osthole were regioselectively semi-prepared. The steric structure of 3c was determined by the X-ray crystal structure. Against Mythimna separata Walker, benzoylhydrazone 3b (R1 = 4-CH3Ph) showed 1.6 folds potent insecticidal activity of the precursor osthole. Introduction of the acylhydrazones on the 3'-methyl-2'-butylenyl fragment at the C-8 position of osthole can improve the insecticidal activity. These will provide a foundation for future structural modifications of osthole as pesticidal agents.Trypanosoma brucei parasites cause Human African Trypanosomiasis and the current drugs for its treatment are often inefficient and toxic. This urges the need to development of new antitrypanosomal agents. We report the synthesis and biological profiling of 3'-deoxy-3'-fluororibonucleosides derived from 7-deazaadenine nucleosides bearing diverse substituents at position 7. They were synthesized through glycosylation of 6-chloro-7-bromo- or -7-iodo-7-deazapurine with protected 3'-fluororibose followed by cross-coupling reactions at position 7 and/or deprotection. Most of the title nucleosides displayed micromolar or submicromolar activity against Trypanosoma brucei brucei. The most active were the 7-bromo- and 7-iododerivatives which exerted double-digit nanomolar activity against T. b. brucei and T. b. gambiense and no cytotoxicity and thus represent promising candidates for further development.An efficient method for the synthesis of substituted 5-(hydroxymethyl)piperazin-2-ones was established by using an automated synthesis process. Thirteen piperazinones were synthesized from chiral α-bromocarboxylic acids and Garner's aldehyde which were prepared by using our originally developed automated synthesizer, ChemKonzert®. The automated method of synthesizing chiral α-bromocarboxylic acids was efficient and safe because the rate of the dropwise addition of the reagent can be controlled using the automated synthesizer. This method is expected to contribute to the synthesis of pharmaceuticals.
The main pathological feature of acute spinal cord injury (ASCI) is neuronal apoptosis and Long non-coding RNA (lncRNA) myocardial infarction-related transcript (MIAT) is involved in the regulation of neuronal apoptosis. This study aimed to investigate the role and potential mechanism of LncRNA MIAT in neuronal apoptosis induced by ASCI.

After Lenti-MIAT lentivirus was microinjected into ASCI rats, Basso, Beattie and Bresnahan Score, Hematoxylin-eosin staining, TUNEL staining, immunohistochemical, immunofluorescence, quantitative real-time PCR and Western blot were used to observe the effect of LncRNA MIAT on the nerve function of ASCI rats. MTT and flow cytometry assays were used to identify the in vitro function of LncRNA MIAT. RNA immunoprecipitation, RNA pull-down, Cycloheximide chase and Chromatin immunoprecipitation combined with qPCR experiments were used to study the mechanism.

The overexpression of LncRNA MIAT was conducive to the recovery of motor function in ASCI rats and repressed neuronal cell apoptosis and increased neuronal cell viability.
