Bioactive compounds and antioxidant activity during ripening of Malpighia glabra fruits.

Malpighia glabra (Malpighiaceae) is a cherry fruit popularly known as acerola or West Indian cherry, with nutraceuticals in each ripening stage. The changes in the phytoconstituents, pigments, sugars, organic acids, and antioxidants were investigated during the fruit ripening and expressed in fresh weight (FW). Gentisic acid was present in the highest concentration in IMGL fruits (11.43 mg/100 g), which was reduced to 0.362 mg/100 g over-ripening. The major flavonoid present was epicatechin, and the concentration increased from 2.11 mg/100 g in immature green large (IMGL) fruits to 19.52 mg/100 g in ripe fruits. Ascorbic acid was the most abundant organic acid present, and the highest concentration was found in the IMGL fruits (2030 mg/100 g). Fructose and galactose were found in the highest concentrations in overripe fruits (2290 mg/100 g and 1460 mg/100 g, respectively). The IMGL fruits showed the highest total antioxidant activity of 5.48% and 5.34% ascorbic acid equivalent in methanolic and aqueous extracts, respectively. Mineral quantification showed that the fruits were rich in potassium and calcium (150.43 and 12.90 mg/100 g, respectively). This study could identify the appropriate stage of acerola fruit for developing functional foods with maximum utilization of phytoconstituents in all stages.

Proceedings of the Ninth Annual Deep Brain Stimulation Think Tank: Advances in Cutting Edge Technologies, Artificial Intelligence, Neuromodulation, Neuroethics, Pain, Interventional Psychiatry, Epilepsy, and Traumatic Brain Injury.

DBS Think Tank IX was held on August 25-27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers (from industry and academia) can freely discuss current and emerging deep brain stimulation (DBS) technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year's meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

Development and validation of a novel corpus of 269 verb pictures in Kannada based on an argument structure taxonomy.

Pictorial stimuli are crucial in psycholinguistic research and clinical practice. The development of culturally and linguistically appropriate, standardized picture corpora is a tedious and meticulous process. Yet, such readily accessible picture sets are useful for researchers and clinicians alike. The current study introduces a novel set of 269 verb pictures for an Indian language - Kannada. The included verbs were selected from a published database of 100,000 words along with their frequency scores in this language, and were subsequently categorized based on an argument structure taxonomy. Each picture is developed based on an exemplar sentence that depicts a scenario rather than a mere action. Norms are provided for verb name and argument agreement, image agreement, concept familiarity, and visual complexity, along with the orthographic frequency. Correlations between these measures are also described. The complete set of pictures are freely downloadable from https://osf.io/uk2af/?view_only=ecffbd92f48546a484c869b3f0b8ec94 for academic, research, and clinical usage in the future.

Neurophysiological brain mapping of human sleep-wake states.

OBJECTIVE: We recently proposed a spectrum-based model of the awake intracranial electroencephalogram (iEEG) (Kalamangalam et al., 2020), based on a publicly-available normative database (Frauscher et al., 2018). The latter has been expanded to include data from non-rapid eye movement (NREM) and rapid eye movement (REM) sleep (von Ellenrieder et al., 2020), and the present work extends our methods to those data. METHODS: Normalized amplitude spectra on semi-logarithmic axes from all four arousal states (wake, N2, N3 and REM) were averaged region-wise and fitted to a multi-component Gaussian distribution. A reduced model comprising five key parameters per brain region was color-coded on to cortical surface models. RESULTS: The lognormal Gaussian mixture model described the iEEG accurately from all brain regions, in all sleep-wake states. There was smooth variation in model parameters as sleep and wake states yielded to each other. Specific observations unrelated to the model were that the primary cortical areas of vision, motor function and audition, in addition to the hippocampus, did not participate in the 'awakening' of the cortex during REM sleep. CONCLUSIONS: Despite the significant differences in the appearance of the time-domain EEG in wakefulness and sleep, the iEEG in all arousal states was successfully described by a parametric spectral model of low dimension. SIGNIFICANCE: Spectral variation in the iEEG is continuous in space (across different cortical regions) and time (stage of circadian cycle), arguing for a 'continuum' hypothesis in the generative processes of sleep and wakefulness in human brain.

Functional Connectivity in Dorsolateral Frontal Cortex: Intracranial Electroencephalogram Study.

Motivation: Mechanisms underlying the variation in the appearance of electroencephalogram (EEG) over human head are not well characterized. We hypothesized that spatial variation of the EEG, being ultimately linked to variations in cortical neurobiology, was dependent on cortical connectivity patterns. Specifically, we explored the relationship of resting-state functional connectivity derived from intracranial EEG (iEEG) data in seven (N = 7) human epilepsy patients with the intrinsic dynamic variability of the local iEEG. We asked whether primary and association brain areas over the lateral frontal lobe-due to their sharply different connectivity patterns-were thus dissociable in "EEG space." Methods: Functional connectivity between pairs of subdural grid electrodes was averaged to yield an electrode connectivity (EC) whose time-average yielded mean electrode connectivity (mEC), compared with that electrode's time-averaged sample entropy (SE; mean electrode sample entropy, mESE). Results: We found that mEC and mESE were generally in inverse proportion to each other. Extreme values of mEC and mESE occurred over the Rolandic region and were part of a more general rostrocaudal gradient observed in all patients, with larger (smaller) values of mEC (mESE) occurring anteriorly. Conclusions: Brain networks influence brain dynamics. Over the lateral frontal lobe, mEC and mESE demonstrate a rostrocaudal topography, consistent with current notions regarding the structural and functional parcellation of the human frontal lobe. Our findings distinguish the frontal association cortex from primary sensorimotor cortex, effectively "diagnosing" Rolandic iEEG independent of the classical mu rhythm associated with the latter brain region. Impact statement Electroencephalographic rhythms (electroencephalogram [EEG]) exhibit well-recognized spatial variation over the brain surface. How such variation pertains to the biology of the cortex is poorly understood. Here we identify a novel relationship between sample entropy of the local EEG and the connectivity of that local cortical region to the rest of the brain. Due to the differing connectivities of primary and association motor areas, our methods identify new differences in the EEG arising from those respective brain areas. Our work demonstrates that aspects of brain dynamics (i.e., EEG entropy) may be understood in terms of brain architecture (i.e., functional connectivity) and vice versa.

Extracranial Interictal and Ictal EEG in sEEG Planning.

Analysis of scalp electroencephalogram (EEG) findings is indispensable to investigation of epilepsy surgery candidates. Maxima of slowing and epileptiform spiking on interictal EEG reflect gross localization of core epileptogenic regions within a network. Important negative scalp EEG findings are those associated with deep foci. Ictal EEG is important in confirming concordance with interictal EEG and other ancillary data. Generalized interictal and ictal EEG findings may occur in epilepsies that are otherwise focal. Detailed individual analyses of scalp EEG features are prelude to a more global synthesis, whose coherence in suggesting plausible network hypothesis presage a subsequently successful scalp EEG evaluation.

Effect of biotic and abiotic elicitors on isoflavone biosynthesis during seed development and in suspension cultures of soybean (Glycine max L.).

The present investigation aimed to look at the effects of biotic and abiotic elicitors during Soybean seed development and cell suspension culture in isoflavones accumulation. The expression levels of four major genes viz., CHS7, CHS8, IFS2, and IFS1 involved on isoflavones biosynthesis during seed developmental stages from R5L-R7 was seen in both MAUS-2 and JS-335 Soybean varieties. The R7 stage showed 1.24-fold upregulation of IFS1transcript level and considered as the control for Soybean seed development. Both varieties during R6-R8 stages responded differently to the foliar application of 10 µM SA, 10 µM MJ and 0.1% Aspergillus niger. The IFS2 transcripts were upregulated by SA at the R7 stage with 5.21- and 4.68-fold in JS-335 and MAUS-2, respectively. IFS1 expression was significantly increased by A. niger treatment at R7 stage with 3.98- and 3.21-fold in MAUS-2 and JS-335, respectively. The expression of CHS7 and CHS8 by 10 µM SA at R7 level revealed maximum up-regulation of 0.51- and 1.01-fold in MAUS-2; 0.37- and 0.82-fold in JS-335, respectively. In the soybean callus suspension culture, biosynthetic genes were used to validate the effects of elicitor on isoflavones. Both biotic and abiotic treatments contribute to the upregulation of IFS1 and IFS2 expression, that in turn, leads to the accumulation of isoflavone in seed development as well as in suspension cultures. These data further suggested that the IFS2 is the key gene responsible for the isoflavone accumulation during elicitor treatment.

A neurophysiological brain map: Spectral parameterization of the human intracranial electroencephalogram.

OBJECTIVE: A library of intracranial electroencephalography (iEEG) from the normal human brain has recently been made publicly available (Frauscher et al., 2018). The library - which we term the Montreal Neurological Institute Atlas (MNIA) - comprises 30 hours of iEEG from over a hundred epilepsy patients. We present a Fourier spectrum-based model of low dimension that summarizes all of MNIA into a neurophysiological 'brain map'. METHODS: Normalized amplitude spectra of the MNIA data were modelled as log-normal distributions around individual canonical Berger frequencies. The latter were concatenated to yield the composite spectrum with high accuracy. Key model parameters were color-coded into a visual representation on cortical surface models. RESULTS: Each brain region has its own spectral characteristics that together yield a novel composite intracranial EEG brain map. CONCLUSIONS: iEEG from normal brain regions can be accurately modelled with a small number of independent parameters. Our model is based in the canonical Berger bands and naturally suits clinical electroencephalography. SIGNIFICANCE: Due to its applicability to iEEG from all sampled regions, the model suggests a certain universality to brain rhythm generation that is independent of precise cortical location. More generally, our results are a novel abstraction of resting cortical dynamics that may help diagnostics in epileptology, in addition to informing structure-function relationships in the field of human brain mapping.

Montages for Noninvasive EEG Recording.

Identifying the localization, distribution, and polarity of waveforms are the prime goals of clinical scalp EEG analysis. Appropriate choices of bipolar and referential montages are keys to emphasizing the diagnostic features of interest, and demand some understanding of the spatiotemporal physical behavior of the underlying neuronal generators. Several examples drawn from canonical epilepsy syndromes are used to illustrate this general message.

Parasitic pneumonia caused by Paragonimus spp. in a wild Royal Bengal Tiger, Mysuru, South India.

Parasitic pneumonia induced by genus Paragonimus involves many species, which affects both humans and animals and it is a food borne zoonotic disease. In this report, we have described the gross and histopathological findings of Paragonimus fluke infection in lungs of tiger. The postmortem examination of sub adult male wild tiger (Panthera tigris tigris) died in captivity was conducted, earlier which was rescued by Forest Department, Mysuru, Karnataka, India. External examination of carcass revealed pale oral and conjunctival mucous membranes with sunken eye balls. During necropsy, moderate congestion, consolidation and numerous transparent to dark encysted lesions were found in the parenchyma of all lobes of lungs visible grossly on pleural surface. Lungs were hemorrhagic with necrotic foci around the cysts. The incision of encysted lesions revealed the presence of flukes (2-3 in numbers) in each cyst with brownish exudate. The lung tissues with lesions were collected in 10% formalin and haematoxylin and eosin staining was done for histopathological evaluation. The flukes were identified as Paragonimus spp. based on the morphology and micrometry. The histopathological examination revealed presence of longitudinal sections of flukes in bronchial lumen (in pair) with tegument and tegumental spines surrounded by connective tissue capsule as cystic encapsulation and numerous eggs in adjacent lung parenchyma. Necrosis and moderate fibrosis of lung parenchyma with infiltration of polymorphonuclear and mononuclear inflammatory cells were observed around fluke as well as eggs. The squamous cell metaplasia of lining bronchial epithelium and atelectasis of alveoli were also prominently seen.

Analysis of Morbidity and Outcomes Associated With Use of Subdural Grids vs Stereoelectroencephalography in Patients With Intractable Epilepsy.

Importance: A major change has occurred in the evaluation of epilepsy with the availability of robotic stereoelectroencephalography (SEEG) for seizure localization. However, the comparative morbidity and outcomes of this minimally invasive procedure relative to traditional subdural electrode (SDE) implantation are unknown. Objective: To perform a comparative analysis of the relative efficacy, procedural morbidity, and epilepsy outcomes consequent to SEEG and SDE in similar patient populations and performed by a single surgeon at 1 center. Design, Setting and Participants: Overall, 239 patients with medically intractable epilepsy underwent 260 consecutive intracranial electroencephalographic procedures to localize their epilepsy. Procedures were performed from November 1, 2004, through June 30, 2017, and data were analyzed in June 2017 and August 2018. Interventions: Implantation of SDE using standard techniques vs SEEG using a stereotactic robot, followed by resection or laser ablation of the seizure focus. Main Outcomes and Measures: Length of surgical procedure, surgical complications, opiate use, and seizure outcomes using the Engel Epilepsy Surgery Outcome Scale. Results: Of the 260 cases included in the study (54.6% female; mean [SD] age at evaluation, 30.3 [13.1] years), the SEEG (n = 121) and SDE (n = 139) groups were similar in age (mean [SD], 30.1 [12.2] vs 30.6 [13.8] years), sex (47.1% vs 43.9% male), numbers of failed anticonvulsants (mean [SD], 5.7 [2.5] vs 5.6 [2.5]), and duration of epilepsy (mean [SD], 16.4 [12.0] vs17.2 [12.1] years). A much greater proportion of SDE vs SEEG cases were lesional (99 [71.2%] vs 53 [43.8%]; P < .001). Seven symptomatic hemorrhagic sequelae (1 with permanent neurological deficit) and 3 infections occurred in the SDE cohort with no clinically relevant complications in the SEEG cohort, a marked difference in complication rates (P = .003). A greater proportion of SDE cases resulted in resection or ablation compared with SEEG cases (127 [91.4%] vs 90 [74.4%]; P < .001). Favorable epilepsy outcomes (Engel class I [free of disabling seizures] or II [rare disabling seizures]) were observed in 57 of 75 SEEG cases (76.0%) and 59 of 108 SDE cases (54.6%; P = .003) amongst patients undergoing resection or ablation, at 1 year. An analysis of only nonlesional cases revealed good outcomes in 27 of 39 cases (69.2%) vs 9 of 26 cases (34.6%) at 12 months in SEEG and SDE cohorts, respectively (P = .006). When considering all patients undergoing evaluation, not just those undergoing definitive procedures, favorable outcomes (Engel class I or II) for SEEG compared with SDE were similar (57 of 121 [47.1%] vs 59 of 139 [42.4%] at 1 year; P = .45). Conclusions and Relevance: This direct comparison of large matched cohorts undergoing SEEG and SDE implantation reveals distinctly better procedural morbidity favoring SEEG. These modalities intrinsically evaluate somewhat different populations, with SEEG being more versatile and applicable to a range of scenarios, including nonlesional and bilateral cases, than SDE. The significantly favorable adverse effect profile of SEEG should factor into decision making when patients with pharmacoresistant epilepsy are considered for intracranial evaluations.

LC-ESI-MS based characterisation of isoflavones in soybean (Glycine max (L.) Merr.) from India.

A total of twenty-one soybean varieties were screened for their morphological characteristics followed by isoflavone content analysis by HPLC. The total isoflavone (TI) content was found within a wide range of 140.9-1048.6 µg/g of soy in different varieties. The highest isoflavone content was found in MAUS-2 followed by DS_2613 and lowest in Karunae (140.9 µg/g of soy). Various isoflavone forms were identified by LC-ESI+ MS. Significant differences in the isoflavone content were observed for all the aglycones and their glucoside conjugates as well as total daidzein, total genistein, total glycitein, and TI. A positive correlation between TI content and growth stages was found during the progression of seed development. An increase of 5.4-fold and 5.3-fold of TI concentration was observed for JS 335 and MAUS-2 respectively, from early to green mature (R5-R8) stage of bean development.

Ictal-Interictal Continuum.

The term "ictal-interictal" continuum has seen wide adoption in the critical care EEG domain, referring to the presence of abnormal periodic activity on the scalp EEG variably associated with seizures. The historical origin of the ictal-interictal continuum concept is discussed with a review of known and surmised physiological mechanisms for their origin and relationship to seizures. Therapeutic approaches to patients exhibiting ictal-interictal continuum EEG patterns are reviewed, and some open scientific questions highlighted. Further understanding of the ictal-interictal continuum is likely to significantly improve the care of the critically ill neurological patient.

Interictal Epileptiform Discharge Detection in EEG in Different Practice Settings.

OBJECTIVE: The goal of the study was to measure the performance of academic and private practice (PP) neurologists in detecting interictal epileptiform discharges in routine scalp EEG recordings. METHODS: Thirty-five EEG scorers (EEGers) participated (19 academic and 16 PP) and marked the location of ETs in 200 30-second EEG segments using a web-based EEG annotation system. All participants provided board certification status, years of Epilepsy Fellowship Training (EFT), and years in practice. The Persyst P13 automated IED detection algorithm was also run on the EEG segments for comparison. RESULTS: Academic EEGers had an average of 1.66 years of EFT versus 0.50 years of EFT for PP EEGers (P < 0.0001) and had higher rates of board certification. Inter-rater agreement for the 35 EEGers was fair. There was higher performance for EEGers in academics, with at least 1.5 years of EFT, and with American Board of Clinical Neurophysiology and American Board of Psychiatry and Neurology-E specialty board certification. The Persyst P13 algorithm at its default setting (perception value = 0.4) did not perform as well at the EEGers, but at substantially higher perception value settings, the algorithm performed almost as well human experts. CONCLUSIONS: Inter-rater agreement among EEGers in both academic and PP settings varies considerably. Practice location, years of EFT, and board certification are associated with significantly higher performance for IED detection in routine scalp EEG. Continued medical education of PP neurologists and neurologists without EFT is needed to improve routine scalp EEG interpretation skills. The performance of automated detection algorithms is approaching that of human experts.

The interictal mesial temporal lobe epilepsy network.

OBJECTIVE: Identification of patient-specific epileptogenic networks is critical to designing successful treatment strategies. Multiple noninvasive methods have been used to characterize epileptogenic networks. However, these methods lack the spatiotemporal resolution to allow precise localization of epileptiform activity. We used intracranial recordings, at much higher spatiotemporal resolution, across a cohort of patients with mesial temporal lobe epilepsy (MTLE) to delineate features common to their epileptogenic networks. We used interictal rather than seizure data because interictal spikes occur more frequently, providing us greater power for analyzing variances in the network. METHODS: Intracranial recordings from 10 medically refractory MTLE patients were analyzed. In each patient, hour-long recordings were selected for having frequent interictal discharges and no ictal events. For all possible pairs of electrodes, conditional probability of the occurrence of interictal spikes within a 150-millisecond bin was computed. These probabilities were used to construct a weighted graph between all electrodes, and the node degree was estimated. To assess the relationship of the highly connected regions in this network to the clinically identified seizure network, logistic regression was used to model the regions that were surgically resected using weighted node degree and number of spikes in each channel as factors. Lastly, the conditional spike probability was normalized and averaged across patients to visualize the MTLE network at group level. RESULTS: We generated the first graph of connectivity across a cohort of MTLE patients using interictal activity. The most consistent connections were hippocampus to amygdala, anterior fusiform cortex to hippocampus, and parahippocampal gyrus projections to amygdala. Additionally, the weighted node degree and number of spikes modeled the brain regions identified as seizure networks by clinicians. SIGNIFICANCE: Apart from identifying interictal measures that can model patient-specific epileptogenic networks, we also produce a group map of network connectivity from a cohort of MTLE patients.

A simple clinical score for prediction of nonepileptic seizures.

Psychogenic nonepileptic seizures (PNES), often mistaken for epilepsy in community practice, require inpatient video-EEG (VEEG) monitoring for diagnostic confirmation. We developed a simple score designed for use in an outpatient setting to predict the subsequent VEEG diagnosis of PNES. We retrospectively compared fifty-five consecutive patients with VEEG-proven PNES (N1=55) with a group of randomly selected patients with VEEG-proven epilepsy (N2=55). Patients were divided into two groups: I) a 'truly retrospective' group of 27 patients with PNES and 27 patients with epilepsy whose data served to develop the score, and II) a 'pseudoprospective' group of 28 patients each with PNES and epilepsy to whom the score was applied. Six features in the history of the Group I cohort appeared more prominent in patients with PNES than patients with epilepsy and were assigned escalating numerical values as follows: number of declared drug allergies (0, 0.5, 1), number of declared comorbidities (0, 0.5, 1), number of previous invasive medical interventions of any type (0, 0.5, 1), and a history of significant psychological or physical trauma (0 or 1). In addition, a score was assigned to verbal description of the seizures themselves as being consistent (=0), atypical (=1), or indeterminate (=0.5) for epilepsy. The values were added to yield an omnibus score ranging from 0 to 6. Scoring of Group II subjects in a blinded fashion revealed that in general patients with PNES had higher scores, and the majority obtained a score >2; most patients with epilepsy scored <1.5. Group difference in the mean between the PNES and epilepsy cohort was highly significant (p<0.0001, Wilcoxon rank-sum test). Our score is a simple clinical instrument based on the patient history that may find use in the triage of patients awaiting hospitalization for VEEG and in pre-VEEG counseling.

Seasonal prevalence of blood parasitic diseases in crossbred cattle of Mysore and its surrounding districts of Karnataka.

The present study report the seasonal prevalence of blood parasitic diseases in cross bred cattle in Mysore and its surrounding districts of Karnataka such as Mandya, Chamaraj Nagar and Kodagu. The study was undertaken for a period of 2 years from August 2013 to July 2015. A total of 1655 blood samples were collected from clinically suspected cattle for blood parasitic diseases with clinical symptoms of anorexia, high fever, anaemia, salivation, enlargement of superficial lymphnodes, haemoglobinuria and sudden drop in milk yield. The blood samples were examined by giemsa's staining technique. Of the 1655 blood samples screened, 673 (40.22%) blood samples were found positive for blood parasites. Amid 673 positive samples, 609 (90.49%), 19 (2.82%) and 45 (6.68%) were found positive for Theileria annulata, Babesia bigemina and Anaplasma marginale respectively. The season wise prevalence revealed that, the highest prevalence was observed in summer months (March-June) (43.17%) followed by rainy (July-October) (39.53%) and winter season (November-February) (39.35%). Further, the month wise prevalence showed highest in August (77.64%) (Rainy month) followed by November (38.23%) and January (35.93%). During August-2013 to July 2014 and between August-2014 and July 2015, the highest was found in the month of May (85%) followed by July (70%) and April (69.81%). Theileriosis was most prevalent in summer (92.73%) followed by rainy (90.95%) and winter season (87.61%). Babesiosis was most prevalent in winter season (5.04%) followed by rainy (1.8%) and summer season (1.7%) whereas, Anaplasmosis was most prevalent in rainy season (7.23%) followed by winter (6.88%) and summer season (5.55%) during two years of study period.

Cobboldia elephantis (Cobbold, 1866) larval infestation in an Indian elephant (Elephas maximus).

In the present study, post-mortem was conducted on a female elephant aged about 37 years died at Rajeev Gandhi National Park, Hunsur, Mathigoodu Elephant Camp, Karnataka state. The animal suffered with diarrhoea, anorexia, dehydration and was unable to walk for about one week before death and was treated with antibiotics and fluid therapy for three days. The post-mortem examination revealed that, the gastric mucosa was severely congested, hyperaemic and numerous stomach bots attached to the mucosa. The bots were recovered from the gastric mucosa and processed for species identification. The posterior spiracles of the bots showed three longitudinal parallel slits in each spiracle, the abdominal segments had a row of belt like triangular shaped spines and the anterior end had two powerful oral hooks with cephalo-pharyngeal skeleton. Based on the above said morphological characters, the bots were identified as Cobboldia elephantis. This seems to be the first report of C. elephantis in free range wild elephant from Karnataka state.

Antioxidant and Cholesterol Esterase Inhibitory Properties of Supplementation with Coconut Water in Submerged Cultivation of the Medicinal Chinese Caterpillar Mushroom, Ophiocordyceps sinensis CS1197 (Ascomycetes).

We investigated the potential use of coconut water to supplement potato dextrose broth (PDB) in the production of Ophiocordyceps sinensis CS1197 by submerged cultivation. The basal PDB medium was modified by supplementation with tender coconut water (TCW) and mature coconut water (MCW) at 10% and 5% (v/v), respectively; these mixtures were cultured at 28°C for 14 days, with a pH of 7 and an inoculum volume of 10%. The addition of optimized levels of TCW and MCW improved the biomass yield by 2.2- and 2.5-fold, respectively, and adenosine, cordycepin, and polysaccharide content by 58% and 69%, 50% and 55%, and 19% and 27%, respectively. Antioxidant and cholesterol esterase (CE) inhibitory activities of the aqueous extract from O. sinensis CS1197 mycelia supplemented with TCW and MCW were high compared with those of the control, indicating that coconut water has a positive correlation with the enhanced antioxidant and CE inhibitory activities. These antioxidant and CE inhibitory responses were dependent on concentration, and the larger amounts of bioactives in O. sinensis CS1197 are beneficial in pharmaceutical formulations.
