Lyngbya C. Agardh ex Gomont is a nonheterocytous cyanobacterial genus whose evolutionary history is still poorly known. The traditionally defined Lyngbya has been demonstrated to be polyphyletic, including at least five distinct clades, some of which have been proposed as new genera. Intraspecific diversity is also clearly underestimated in Lyngbya due to the lack of unique morphological characters to differentiate species. In this study, we describe the new genus Capillus T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes from benthic marine environments, including two new Brazilian species (here described as C. salinus T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes, and C. tropicalis T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes), and two species yet to be described, one of them from India (Capillus sp. 2.1), and the other from United States of America, based on strain PCC 7419. Capillus species presented cross-wise diagonal fragmentation, assisted or not by necridic cells, which has not been previously mentioned for Lyngbya. Ultrastructural analyses showed that C. salinus and C. tropicalis have numerous gas vesicles, which are rarely described for benthic marine species. The new genus formed a well-supported clade, and the D1-D1' and Box B secondary structures of internal transcribed spacer also supported the proposal of its new species. These findings help to clarify the diversity of species in the Lyngbya complex and the taxonomy of the group, and highlight the need of further floristic surveys in tropical coastal environments, which remain poorly studied.

Treatment of Masticatory Muscle Pain with Acupuncture: Is It Necessary to Associate with Occlusal Splints?

Crischina Branco Marques Sant’Anna,Fernanda Pereira de Caxias,Paulo Renato Junqueira Zuim,Marcella Santos Januzzi,Emily Viviane Freitas da Silva,Karina Helga Leal Turcio 사단법인약침학회 2021 Journal of Acupuncture & Meridian Studies Vol.14 No.3

Background: Temporomandibular disorders (TMDs) are treated by different modalities including splints, physiotherapy, and acupuncture. Although all of these offer evidencebased benefits to the patients, avoiding overtreatment is of paramount importance. Objectives: To assess the effectiveness of muscle pain treatment with acupuncture combined with or without occlusal splints. Methods: Recruited patients were allocated to G1 (acupuncture) and G2 (acupuncture and occlusal splint) groups and treated in four consecutive weekly sessions (P1, P2, P3, and P4). The reported pain (RP) and the pressure pain threshold (PPT) of the masseter and temporalis muscles were assessed before and after each session. Results: RP decreased after each session in G1, except at P4. In G2, the RP decreased only after the first session, and the PPT did not vary. Conclusion: The assessed treatments did not influence the PPT levels of the masseter and anterior temporalis muscles in patients with temporomandibular disorders. Our findings suggest that occlusal splints may not be mandatory along with the acupuncture treatment.

This study aimed to assess the effects of a yacon-based product (YBP) on constipation in adults, including the elderly. Forty-eight individuals were recruited and divided into equal intervention groups named the test and control groups. The YBP (test) and the control (maltodextrin) were dissolved in commercial orange juice. The volunteers for the YBP/test group consumed, on a daily basis, orange juice containing 10 g fructooligosaccharide (FOS)/inulin per day. The control group consumed, on a daily basis, orange juice containing 25 g of maltodextrin. The study had a span of 30 days. We evaluated the participants’ frequency of evacuation, consistency of the feces, constipation score, abdominal symptoms (flatulence, pain, and abdominal strain), and effects upon the microbiota, pH, lactate, and short-chain fatty acids (SCFAs) of the feces. The study showed an increased number of evacuations after the consumption of the YBP as well as an improvement in the consistency of the feces and a reduction in the constipation score. After 30 days of intervention, the group that consumed the YBP showed higher counts of Bifidobacterium, lower Clostridium and enterobacteria counts, and lower fecal pH. In relation to SCFAs, no significant change was found after the intervention. However, the lactate concentration was higher in the test group when compared to the post-treatment control group. The YBP was effective in improving constipation symptoms; not only was its functional characteristic in reducing constipation symptoms evident but it also demonstrated usefulness as a potential therapy.

Paresthesia is defined as an alteration in local sensibility, associated with numbness, tingling, or unpleasant sensations caused by nerve lesions or irritation. It can be temporary or permanent. The treatment protocol for facial paresthesia is primarily based on the use of drugs and implant removal, which may not be completely effective or may require other risk exposure when there is no spontaneous regression. However, other therapeutic modalities such as acupuncture can be used. The aim of this study is to report a case of a patient with paresthesia of the inferior alveolar nerve and pain caused by an implant surgery performed 2 years earlier. The patient received acupuncture treatment during 4 months of weekly sessions. Six points were used: Large Intestine (LI4), Large Intestine (LI11), Stomach (ST36), Liver (LR3), Extra Head and Neck (E-HN-18), and Stomach (ST5). The visual analog scale was used before and after each session for the analysis of paresthesia and pain, together with assessment of the paresthesia by delimitation of the desensitized region of the skin and presented discomfort. Pain remission and reduction in the size of the paresthesia area occurred after four sessions.

Ustekinumab for the treatment of refractory pediatric Crohn’s disease: a single-center experience

( Alexandra Cohen ),( Najma Ahmed ),( Ana Sant’anna ) 대한장연구학회 2021 Intestinal Research Vol.19 No.2

Background/Aims: Despite the well-established efficacy of tumor necrosis factor (TNF) antagonists as treatment options for Crohn’s disease, many pediatric patients need a change in therapy due to adverse events and loss of response, highlighting the necessity for medications with a different mechanism of action. Ustekinumab has been shown to be effective in inducing clinical remission in some adults with disease refractory to anti-TNF agents, however, minimal data exists in the pediatric population. Methods: We conducted a retrospective chart review of 11 pediatric patients receiving ustekinumab, specifically extracting baseline data, information on prior treatment and response, indications for starting ustekinumab, clinical information, and laboratory parameters pre- and post-therapy. Clinical response was defined as a decrease in abbreviated Pediatric Crohn’s Disease Activity Index score. Results: Patients ranged from 12 to 17 years of age upon initiation of treatment with ustekinumab. Five of 11 patients demonstrated a clinical response. Among these patients, 2 remained in clinical remission, while the remaining 3 experienced a secondary loss of response. The other 6 patients were primary nonresponders who either remained unwell or demonstrated slight clinical worsening. All patients who clinically responded to ustekinumab and had an initially elevated CRP experienced complete normalization of their values. Mucosal healing was seen on endoscopy in 1 responder, with 2 other patients showing endoscopic improvement. Conclusions: These results demonstrate for the first time that ustekinumab has the potential to induce not only clinical and biochemical remission, but also endoscopic improvement, in the pediatric population. Future research is needed to determine factors that influence response to therapy. (Intest Res 2021;19:217-224)

In this work, we attempted to assess the effects of inoculation of arbuscular mycorrhizal fungus (AMF),Glomus clarum, on the survival and development of micropropagated Jatropha curcas plantlets at different rooting stages. Elongated shoots (average 3 cm) of J. curcas,maintained for 0, 14, or 21 days on rooting medium in the presence or absence of 1 mg L-1 indole-3-butyric acid (IBA), were transferred to a sand:soil:vermiculite (1:1/2:1)(v:v:v) substrate. At the time of transplantation, the plantlets were either inoculated or not inoculated with G. clarum that had been monoaxenically produced in Ri-transformed carrot roots. After a 2-week acclimatization period, 100 %of the plants kept for 0 or 14 days in rooting medium survived. However, those that remained for 21 days in rooting medium displayed post-acclimatization survival rates of 93 and 89 % for plants inoculated and non-inoculated with G. clarum, respectively. Colonization rates ranged from 70 to 93 %, and the stimulatory effects of AMF were evidenced by increased phosphorus uptake by plants and increases in all evaluated growth parameters,except plant height. Plants that were not subjected to the rooting stage showed growth similar to or higher than those subjected to the rooting stage, regardless of the addition of IBA. It can be concluded that stimulatory effects of mycorrhizal fungi were observed, and that the inoculation of J. curcas proved effective during the initial period of the acclimatization phase.

Objective: Evidence has suggested that immune imbalance is involved with bipolar disorder (BD); however, its precise mechanism is poorly understood. This study investigated whether biochemical changes in the serum from BD patients could modulate the phenotype of cultured macrophages. Methods: Eighteen subjects with BD and five healthy individuals were included in this study. The human monocyte cell line U-937 was activated with phorbol 12-myristate 13-acetate (PMA) and polarization was induced with RPMI-1640 media supplemented with 10% serum from each patient for 24 hours. Gene expression of selected M1 and M2 markers was assessed by quantitative PCR. Results: Macrophages exposed to serum of manic and depressive BD patients displayed an increase of interleukin-1 (6.40±3.47 and 9.04±5.84 vs. 0.23±0.11; p<0.05) and tumor necrosis factor- (2.23±0.91 and 2.03±0.45 vs. 0.62±0.24; p=0.002 and p=0.004, respectively) compared to euthymic group (there was no difference between euthymic and controls). In parallel, U-937 macrophages treated with serum of patients in acute episode displayed a down-regulation of CXCL9 (0.29±0.20 vs. 1.86±1.61; p=0.006) and CXCL10 expression (0.36±0.15 and 0.86±0.24 vs. 1.83±0.88; p<0.000 and p=0.04) compared to the euthymia group. Conclusion: Our results are consistent with previous studies showing that changes in peripheral blood markers could modulate M1/M2 polarization in BD. The evidence of macrophages as source of inflammatory cytokines might be helpful to unravel how the mononuclear phagocyte system is involved in the etiology of BD.
