Abstract
(1) Background: Hypertension is a serious medical condition characterized by a persistent increase in blood pressure (BP), which is prevalent in individuals with knee osteoarthritis (KOA). Pharmacological interventions are normally used to treat both hypertension and KOA; however, a more sustainable form of treatment is desirable for these clinical conditions. Whole-body vibration (WBV) exercise has been proposed as a non-pharmacological therapy for reducing both BP and KOA symptomatology. This study aimed to evaluate the antihypertensive effect of WBV in hypertensive individuals with KOA. (2) Methods: Nineteen hypertensive individuals with KOA were randomly allocated to either a control (CG) (n = 9) or a WBV group (WBVG) (n = 10). Subjects in the WBVG were positioned sitting in a chair in front of a vibrating platform (VP) with the feet on the base (peak-to-peak displacement 2.5, 5.0 and 7.5 mm; frequencies 5 to 14 Hz). In the CG, subjects assumed the same position with the VP turned off. The protocols in the CG and WBVG were performed 2 days/week for a total of 5 weeks. (3) Results: No baseline differences (age, anthropometrics, BP parameters and medications) between the groups were found (p > 0.05). WBV exercise reduced systolic BP (SBP: 126.1 +/- 2.7 versus 119.1 +/- 3.2 mmHg; p = 0.001; post hoc: p = 0.02; F = 23.97) and mean BP (MBP: 82.6 +/- 1.8 versus 78.7 +/- 1.8, p = 0.001, post hoc: p = 0.02; F = 23.97), while no significant changes were found in diastolic BP (DBP: 68.5 +/- 2.2 versus 64.4 +/- 2.3; p = 0.11; F = 2.68). (4) Conclusions: WBV might be considered a sustainable therapy for exerting an antihypertensive effect in medicated hypertensive individuals with KOA. This decline in BP might translate to a reduction in pharmacological need, although further studies are necessary to understand the mechanisms underlying the described effect.

Abstract
In the current study, we report the high-quality draft genome sequence ofNeonectriasp. DH2, an endophytic fungus isolated fromMeconopsis grandisPrain in Tibet. The whole genome is about 45.8 Mbp, with a GC content of 53%. A total of 14,163 genes are predicted to encode proteins, and 557 of them are considered as unique, as no matches are found in five gene databases. A neighbor-joining phylogenetic tree based on internal transcribed spacer (ITS) region sequences shows thatNeonectriasp. DH2 was most closely related toNeonectria ramulariae. 47 biosynthetic gene clusters (BGC) were identified inNeonectriasp. DH2 genome, and only 5 BGCs shows significant similarities to previously reported BGCs. The presence of 42 unique BGCs inNeonectriasp. DH2 suggests that it has great potential to produce novel secondary metabolites.
