RESUMEN

OBJECTIVE: This study aimed to examine the effects of mindfulness-based stress reduction (MBSR) in patients with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PPCI). METHODS: A retrospective study was conducted with data collected from AMI patients who underwent successful PPCI. The study included 61 cases that received 8-week MBSR intervention (MBSR group) and 61 cases that received weekly health education (control group) over the same period. Outcome measures, including hemodynamic parameters, psychosocial characteristics [Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS), Perceived Social Support Scale (PSSS)], health-related quality of life [HRQoL, 7-item Seattle Angina Questionnaire (SAQ-7)], and major adverse cardiovascular events (MACE), were assessed at baseline (T1), post-intervention (T2), 1 month after the post-intervention (T3) and 3 months after the post-intervention (T4). RESULTS: Compared to the control group, the MBSR group showed improvements in blood pressure, specifically in systolic blood pressure (SBP) at T4, and diastolic blood pressure (DBP) at T3 and T4, and mean arterial blood pressure (MABP) at T3 and T4. Additionally, the MBSR group had lower scores of anxiety and perceived stress (HADS, PSS) and higher scores of perceived social support (PSSS) after the intervention. Furthermore, the MBSR group had higher scores on the SAQ-7 at all measurement points. The control group had a significantly higher total MACE rate compared to the MBSR group (26.23% vs. 9.84%). CONCLUSIONS: This study provides support for the potential benefits of MBSR as an adjunctive treatment for AMI patients undergoing PPCI.

RESUMEN

Objective To investigate the expression of α-smooth muscle actin(α-SMA)in advanced colorectal cancer tissue and its association with chemotherapy response and prognosis.Methods The expression of α-SMA was detected by immunohistochemistry in tissues from 52 advanced colorectal cancer patients who received oxaliplatin plus 5-fluorouracil regimen as first-line chemotherapy. Its relationship with clinical characteristics,chemotherapy response,and survival were analyzed.Results Of these 52 patients,29(55.8%)were α-SMA overexpression,and the expression of α-SMA protein was not significantly associated with the age(χ 2=0.113,P=0.730),gender(χ 2=0.515,P=0.332),tumor location(χ 2=3.675,P=0.159),and tissue differentiation(χ 2=1.852,P=0.604). The chemotherapy resistance rate was 65.5%(19/29)in patients with high α-SMA expression,which was significantly higher than that (13.0%,3/23)in patients with low α-SMA expression(χ 2=14.470,P=0.000). Patients with high α-SMA expression exhibited a significantly shorter progression-free survival(PFS)compared with those with low α-SMA expression [(6.4±1.0)months vs.(16.0±3.5)months; χlog-rank2=5.985,P=0.018]. Conclusion High α-SMA expression is associated with resistance to first-line chemotherapy and poor prognosis in advanced colorectal cancer patients.

RESUMEN

Behaviors are challenging to reconstruct for extinct species, particularly the nature and origins of acoustic communication. Here we unravel the song of Archaboilus musicus Gu, Engel and Ren sp. nov., a 165 million year old stridulating katydid. From the exceptionally preserved morphology of its stridulatory apparatus in the forewings and phylogenetic comparison with extant species, we reveal that A. musicus radiated pure-tone (musical) songs using a resonant mechanism tuned at a frequency of 6.4 kHz. Contrary to previous scenarios, musical songs were an early innovation, preceding the broad-bandwidth songs of extant katydids. Providing an accurate insight into paleoacoustic ecology, the low-frequency musical song of A. musicus was well-adapted to communication in the lightly cluttered environment of the mid-Jurassic forest produced by coniferous trees and giant ferns, suggesting that reptilian, amphibian, and mammalian insectivores could have also heard A. musicus' song.

RESUMEN

The abundance of insects in Burmese amber illustrates a highly diverse insect community from the mid-Cretaceous period; yet, records of crickets (Grylloidea) are notably scarce. In this study, we describe two new genera with three new species, Palaeotrigonidium concavoculus gen. et sp. nov., Palaeotrigonidium defectivus sp. nov., and Tricalcaratus longilineus gen. et sp. nov., based on three specimens collected in north Myanmar. These new species can be placed within the Trigonidiidae (Orthoptera: Grylloidea) by their triangular head, compound eyes that protrude in dorsal view, and a body entirely covered with robust setae, particularly noticeable in the head and pronotum; however, subfamily assignments are not possible. Another known species, Birmaninemobius hirsutus, Xu et al., 2020, from Myanmar amber is redescribed based on a new specimen and a recheck of the holotype.

RESUMEN

A phylogeny of Cyrtophyllitinae Zeuner, 1935 sensu Gorochov, Jarzembowski & Coram, 2006, based on wing morphology, is presented including all genera. Cyrtophillitinae is found to be paraphyletic. Except for Cyrtophyllites rogeri Oppenheim, 1888, all other species were moved from the subfamily Cyrtophyllitinae (Hagloidea, Haglidae). Consequently, a new subfamily Archaboilinae subfam. nov. was erected and accommodates most of the previous cyrtophillitine taxa, except Cyrtophyllites rogeri. The type genus Archaboilus Martynov, 1937 of the new subfamily was designated; a new genus, Pararchaboilus gen. nov., was erected with the designation of type species Pararchaboilus cretaceus comb. nov. From the Middle Jurassic deposits of China, two new species, Archaboilus ornatus sp. nov. and Vitimoilus gigantus sp. nov., are described.

RESUMEN

The article describes two new species of Trigonidiidae Saussure, 1874, namely Pteronemobius yuani Ma & Wang sp. nov. and Metiochodes tianfuensis Ma, Yuan & Gu sp. nov. The former belongs to Pteronemobius Jacobson, 1904, and is similar to Pteronemobius gifuensis (Shiraki, 1911) but has a long and narrow epiphallic median lobe, and the outer posterior tibia is armed with three dorsal spurs; while the latter belongs to Metiochodes Chopard, 1932, which is similar to Metiochodes flavescens Chopard, 1932, but the epiphallic median lobe is concave. Here, we describe and illustrate these new species.

RESUMEN

Mitius was initially described by Gorochov in 1985, using Gryllus flavipes (=Mitius flavipes) Chopard, 1928 as the type species. To date, nine species have been discovered across the world (Storozhenko, Kim Jeon, 2015; Cigliano et al. 2021). Mitius castaneus (Chopard, 1937) and Mitius vaturu (Otte Cowper, 2007) have truncate frons similar to Loxoblemmus Saussure, 1877, while the remaining seven species (Mitius blennus (Saussure, 1877), Mitius enatus Gorochov, 1994, Mitius eryuanensis Yuan, Xie Liu, 2021, M. flavipes, Mitius minor (Shiraki, 1911), Mitius minutulus Yang Yang, 1995, and Mitius splendens (Shiraki, 1930)) have a standard round frons. A new species with truncate frons that was discovered in Xizang autonomous region, China is described and illustrated in this paper.

RESUMEN

We revise the subfamily Zeuneropterinae (Orthoptera, Ensifera) and treat it as the family Palaeorehniidae Zeuner stat. nov. We restore the late Eocene Palaeorehnia Cockerell from Florissant, Colorado, USA to the taxon and describe two new genera and species in it: Ypopteron nicola n. gen., n. sp. from Quilchena, British Columbia, Canada and Republicopteron douseae n. gen., n. sp. from Republic, Washington, USA. Given current knowledge, Palaeorehniidae appears intermediate between the Stenopelmatoidea and the Hagoidea (s.s.).

RESUMEN

The abundance of insects in Burmese amber illustrates a highly diverse orthoptera community of the mid-Cretaceous, but the records of ripipterygids are relatively rare. Here, we reviewed the genus of Magnidactylus (Xu, Fang and Jarzembowski, 2020) and transfered it from Tridactylidae to Ripipterygidae. Based on four ambers specimens collected from northern Myanmar, two new species, Magnidactylusmirus sp. nov. and Magnidactylusgracilis sp. nov., wereerected. M.mirus sp. nov. can be characterized by its basal segment and apical segment of paraproctal lobes, which are equally thick and clavate. M.gracilis sp. nov. can be characterized by its apical segment of paraproctal lobes, which are distinctly swollen. Additionally, in order to facilitate the classification of amber specimens of Tridactyloidea, a key to the genera ofambers in this superfamily is provided.

RESUMEN

The abundance of insects in Burmese amber illustrates a highly diverse insect community of the mid-Cretaceous, but the records of crickets are relatively rare. Here, we erect two new genera with two new species, Birmanioecanthus haplostichus gen. et sp. nov. and Apiculatus cretaceus gen. et sp. nov., based on two new specimens from northern Myanmar amber. These new species can be assigned to the subfamily Oecanthinae (Orthoptera: Gryllidae) by their prognathous head, slender body and metatibiae, and protibiae with large tympana. These new findings are the first and earliest fossil record of tree crickets and shed light on the evolution of Oecanithinae.

RESUMEN

A new species of Cyrtophyllitinae, Archaboilus polyneurus sp. nov. Gu, Yue & Ren, is described from the Middle Jurassic Jiulongshan Formation, Daohugou Village, Inner Mongolia, China. The species is characterized by its ScA reaching the anterior wing margin at the level of the divergence of M+ CuA, distally branched RP, lengths of free CuA and free M equal, and numerous branches of CuA + CuPaα. A new fossil of Liassophyllum caii Gu & Ren, 2012 is described which increases knowledge of its wing venation and indicates that Liassophyllum should be assigned to the Tuphellidae.

RESUMEN

A high portion of the earliest known insect fauna is composed of the so-called 'lobeattid insects', whose systematic affinities and role as foliage feeders remain debated. We investigated hundreds of samples of a new lobeattid species from the Xiaheyan locality using a combination of photographic techniques, including reflectance transforming imaging, geometric morphometrics, and biomechanics to document its morphology, and infer its phylogenetic position and ecological role. Ctenoptilus frequens sp. nov. possessed a sword-shaped ovipositor with valves interlocked by two ball-and-socket mechanisms, lacked jumping hind-legs, and certain wing venation features. This combination of characters unambiguously supports lobeattids as stem relatives of all living Orthoptera (crickets, grasshoppers, katydids). Given the herein presented and other remains, it follows that this group experienced an early diversification and, additionally, occurred in high individual numbers. The ovipositor shape indicates that ground was the preferred substrate for eggs. Visible mouthparts made it possible to assess the efficiency of the mandibular food uptake system in comparison to a wide array of extant species. The new species was likely omnivorous which explains the paucity of external damage on contemporaneous plant foliage.

RESUMEN

A new fossil genus and species is described from the Middle Jurassic of China. The type of Sinoelcana minuta gen. et sp. nov. has body and legs preserved. It is distinguished from all other elcanids by the unique combination of wing venation and stout ovipositor. The sickle-shaped ovipositor suggests that the new species had a preference for oviposition on plant material. A world key to the genera of Elcanidae is provided based on the wing venation.

RESUMEN

A new species of Elcanidae (Orthoptera, Elcanoidea), Parelcana pulchmacula sp. nov., is described based on four new specimens from the Middle Jurassic Jiulongshan Formation of northeastern China. The new species differs from all other known Archelcaninae species by its combination of wing-venation characters. This new finding improves our knowledge of variation on wing venation in elcanid insects and constitutes the first record of Elcanidae from the Daohugou fossil bed (Yanliao Biota) of northeastern China.

RESUMEN

Development of a photosensitizer that can achieve tumor specificity, improve therapeutic efficacy, and reduce side effects remains a challenge for photodynamic therapy (PDT). In this work, a pH-sensitive activatable nanophotosensitizer (SMSN-ZnPc1) has been elaborately designed, which could be readily prepared by using a functionalized zinc(ii) phthalocyanine (ZnPc) to conjugate with stellate mesoporous silica nanoparticles (SMSNs) through an acid-sensitive hydrazone bond. Meanwhile, a non-activatable analogue SMSN-ZnPc2 has also been prepared as a negative control. The fluorescence emission and singlet oxygen generation of the photosensitizer are essentially quenched in the intact nanophotosensitizer. However, these properties of SMSN-ZnPc1 can be restored greatly both in acidic solutions and at the cellular level. More importantly, after intravenous administration, SMSN-ZnPc1 can also be selectively activated at the tumor site and exhibit efficient tumor growth inhibition in S180 rat ascitic tumor-bearing KM mice with negligible systemic toxicity. It thus may serve as a promising nanoplatform for cancer diagnosis and targeted PDT.
