[PMID: 38198469 PMCID: PMC10783825 DOI: 10.1080/15502783.2024.2302046] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 12/31/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, flurbiprofen, naproxen sodium, and indomethacin are commonly employed for their pain-relieving and inflammation-reducing qualities. NSAIDs work by blocking COX-1 and/or COX-2, enzymes which play roles in inflammation, fever, and pain. The main difference among NSAIDs lies in their affinity to these enzymes, which in turn, influences prostaglandin secretion, and skeletal muscle growth and regeneration. The current study investigated the effects of NSAIDs on human skeletal muscle cells, focusing on myoblast proliferation, differentiation, and muscle protein synthesis signaling. METHODS Using human primary muscle cells, we examined the dose-response impact of flurbiprofen (25-200 µM), indomethacin (25-200 µM), ibuprofen (25-200 µM), and naproxen sodium (25-200 µM), on myoblast viability, myotube area, fusion, and prostaglandin production. RESULTS We found that supraphysiological concentrations of indomethacin inhibited myoblast proliferation (-74 ± 2% with 200 µM; -53 ± 3% with 100 µM; both p < 0.05) compared to control cells and impaired protein synthesis signaling pathways in myotubes, but only attenuated myotube fusion at the highest concentrations (-18 ± 2% with 200 µM, p < 0.05) compared to control myotubes. On the other hand, ibuprofen had no such effects. Naproxen sodium only increased cell proliferation at low concentrations (+36 ± 2% with 25 µM, p < 0.05), and flurbiprofen exhibited divergent impacts depending on the concentration whereby low concentrations improved cell proliferation (+17 ± 1% with 25 µM, p < 0.05) but high concentrations inhibited cell proliferation (-32 ± 1% with 200 µM, p < 0.05). CONCLUSION Our findings suggest that indomethacin, at high concentrations, may detrimentally affect myoblast proliferation and differentiation via an AKT-dependent mechanism, and thus provide new understanding of NSAIDs' effects on skeletal muscle cell development.

J Sci Med Sport 2024:S1440-2440(24)00486-9. [PMID: 39209691 DOI: 10.1016/j.jsams.2024.08.201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 07/23/2024] [Accepted: 08/10/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVES Investigate the association between injury severity and sports-related analgesic use, and explore the types and reasons for analgesic use in Danish youth elite athletes. DESIGN 4-week prospective cohort study. METHODS 713 youth elite athletes (44 % female) aged 15-20 years provided information on demographics, sports specific questions, and injury severity. We categorized injury severity based on the amount of impact on sports participation: 1) no injury (reference), 2) injury not affecting sports participation, 3) injury causing modifications in sports participation, and 4) injury causing complete absence from sport. Participants were asked weekly over 4 weeks about the number of days with sports-related analgesic use, types, and reasons for use. Mixed-effects regression models were used to assess the association between injury severity and prevalence (yes/no) and frequency (days/week) of analgesic use. RESULTS Analgesic use at least once during the four weeks was reported by 224 athletes (31 %), with a mean weekly prevalence of 13 %. The odds of analgesic use increased with injury severity compared with the reference group; injury not affecting sports participation: OR 2.6 (95 % CI 1.6-4.2), injury causing modifications in sports participation: OR 3.2 (95 % CI 2.0-5.2), injury causing complete absence from sport: OR 3.6 (95 % CI 1.5-8.7) (test for trend; p = <0.001). The rate (frequency) of analgesic use also increased with injury severity (test for trend; p = 0.003). Athletes most commonly used analgesics to treat pain/injury after sports participation (62 %), and paracetamol was most frequently used (84 %). CONCLUSIONS Injury severity was associated with increased odds and rate of analgesic use.

Abstract
OBJECTIVE This cross-sectional study evaluated de-identified data from the National Collegiate Athletic Association-Department of Defense Grand Alliance from 2014 to 2020 to determine the prevalence of migraine and migraine medication and to describe differences in migraine prevalence by sex, race, and sport. BACKGROUND Epidemiological studies can help identify underdiagnosed and undertreated populations. Understanding migraine prevalence in collegiate student-athletes is essential for positive healthcare outcomes including development of prevention and treatment plans. METHODS From a concussion baseline assessment, participant's self-reported demographics (e.g., age, sex, sport), migraine diagnosis (i.e., yes/no), and migraine medication usage (e.g., yes/no, type) determined prevalence of migraine and medication use in collegiate student-athletes. RESULTS Migraine was reported in 5.6% (2617/47,060; 95% confidence interval [CI] 5.4%-5.8%) of the student-athletes, with higher prevalence in females, 7.5% (1319/17,628; 95% CI 7.1%-7.9%), than males, 4.6% (1298/28,116; 95% CI 4.4%-4.9%). Medication usage was reported by 36.2% (947/2617; 95% CI 34.3%-38.0%) of individuals with migraine. Migraine reporting differed by race, with Caucasian reporting highest (5.9%; 1990/33,913; 95% CI 5.6%-6.1%) and Asian the lowest (2.7%; 55/2027; 95% CI 2.1%-3.5%). Women's sports, including golf, gymnastics, and lacrosse, and men's diving and squash had higher migraine reporting than other sports. CONCLUSION Caucasian females reported higher rates than other groups and sport influenced rates of migraine diagnosis.

BMJ Open Sport Exerc Med 2024; 10:e001941.

Abstract
Amateur football coaches play a key role in preventing, assessing and treating pain among their players, as they are often the first point of contact and may be the main source of advice and guidance. The objective of this study was to explore amateur football coaches' perceptions of pain during sports participation and their approach to pain management. We conducted a qualitative interview study with 20 amateur football coaches from a strategically selected sample of male and female, and junior and senior teams. A semistructured interview guide and conventional qualitative content analysis were used. One overall theme emerged: To play or not to play-coaches navigating difficult terrain with limited resources. The theme included four main categories: How can pain be understood?; Can pain be avoided?; How to manage players with pain?; What resources do we need? Different ways of understanding pain emerged, and coaches described that players have different pain thresholds. Pain was seen as a part of the game that cannot be completely avoided. In general, there was a restrictive attitude regarding pain medication, though actual consumption was not known. Coaches emphasised shared responsibility with players to achieve adequate training loads, a positive communication climate surrounding pain, and a need for education and competence. In conclusion, coaches expressed various interpretations of pain during sports participation and pain management, where they need to take on great responsibility despite limited medical competence. Coaches believed that adequate pain management is important, and their keys to reducing the risk of pain included structured and customised training, a well-balanced training load and recovery, and a positive communication climate in the team. Coaches often decide whether players experiencing pain can participate in team training and match play, emphasising the need for education support and access to medical competence.

Abstract
Previous works have suggested a high prevalence of painkiller intake (PI) among sport students but also improved health literacy (HL) for sports-active students than for sports-inactive students. Since health-related content also forms part of the sport science curriculum, the study focuses on these seemingly paradoxical results. Music students who are also physically active through their instrumental practice, who act in an area with increased PI and who have no health-related teaching content in their curriculum composed the comparison group. Therefore, this study investigated the prevalence of PI and HL in cohorts of sport (n = 222; 54.5% female) and music students (n = 89; 67.4% female) using a cross-sectional online survey in Lower Saxony, Germany. The hypothesis tests were validated by calculating frequentist and Bayesian statistics. The results show that 50.9% of sport and 28.1% of music students exhibit PI concerning their study programs, often for prophylactical purposes and in the presence of low HL levels. The weak negative correlation between PI and HL was not statistically confirmed and requires further research with improved test power. Regarding the possible health consequences of an inconsiderate PI, target group-specific prevention is indicated to increase general health awareness and HL.

NSAIDs do not prevent exercise-induced performance deficits or alleviate muscle soreness: A placebo-controlled randomized, double-blinded, cross-over study. J Sci Med Sport 2024; 27:287-292. [PMID: 38383211 DOI: 10.1016/j.jsams.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 01/16/2024] [Accepted: 02/06/2024] [Indexed: 02/23/2024]
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently consumed by athletes to manage muscle soreness, expedite recovery, or improve performance. Despite the prevalence of NSAID use, their effects on muscle soreness and performance, particularly when administered prophylactically, remain unclear. This randomized, double-blind, counter-balanced, crossover study examined the effect of consuming a single dose of each of three NSAIDs (celecoxib, 200 mg; ibuprofen, 800 mg; flurbiprofen, 100 mg) or placebo 2 h before on muscle soreness and performance following an acute plyometric training session. Twelve healthy adults, aged 18-42 years, completed a standardized plyometric exercise session consisting of 10 sets of 10 repetitions at 40 % 1-repetition maximum (1RM) on a leg press device. During exercise, total work, rating of perceived exertion, and heart rate were measured. Maximum voluntary contraction force (MVC), vertical jump height, and muscle soreness were measured before exercise and 4-h and 24-h post-exercise. We found no significant differences in total work, heart rate, or rating of perceived exertion between treatments. Additionally, no significant differences in muscle soreness or vertical jump were observed between treatments. Ibuprofen and flurbiprofen did not prevent decrements in MVC, but celecoxib attenuated decreases in MVC 4-h post exercise (p < 0.05). This study suggests that athletes may not benefit from prophylactic ibuprofen or flurbiprofen treatment to prevent discomfort or performance decrements associated with exercise, but celecoxib may mitigate short-term performance decrements.

Abstract
OBJECTIVES To determine the prevalence and intensity of pain due to a football-related injury during activities of daily living and during training and/or match play in both male and female and youth and adult amateur players. DESIGN A prospective cohort study involving amateur football players. METHODS Players (n = 502, median age 18 years, range 14-46) responded to weekly questionnaires during one season, including the Oslo Sports Trauma Research Center Overuse Injury Questionnaire. Weekly pain prevalence and pain intensity (measured on the numeric rating scale [range 0-10]) during activities of daily living and while playing football were determined. RESULTS A total of 6601 weekly questionnaires were collected (response rate 63.7 %). Average weekly pain prevalence during activities of daily living was 17.2 % for all players, and 15.7 % among players who participated in training and/or match play. Pain prevalence during training and/or match play was 18.3 % with an average pain intensity of 4.0. In 21.3 % of cases the recorded pain intensity was >5. Sex, age, and mode of injury onset (sudden or gradual) were not significant predictors of pain intensity. CONCLUSION At a given week, one in six football players experiences pain during activities of daily living from a football-related injury. Almost one in five players reports pain while playing football, of whom >20% report a pain intensity above 5. Oftentimes, injury-related pain present while playing football transcends to activities of daily living. This warrants further monitoring and adequate management of pain within amateur football.

Abstract
BACKGROUND Athletes are injured frequently and often take analgesic medication. Moreover, athletes commonly use non-prescription topical and oral medications with little guidance. Despite wide use, relatively few studies exist on the efficacy of pain medication in injured athletes compared to a placebo. OBJECTIVE To determine efficacy of topical or oral medications in pain reduction compared to a placebo in injured athletes. STUDY DESIGN A systematic review and meta-analysis. METHODS We conducted an electronic search using Medline/Pubmed, Web of Science, Ovid, and SportDiscus for all literature relating to topical or oral medications in athletes for pain management post-injury. Two reviewers screened the studies and measured their quality. To determine efficacy, we calculated the Hedges' g value. We created forest plots with 95% CI to graphically summarize the meta-analyses. RESULTS There was a significant pooled effect size reflecting a reduction in pain outcomes for the topical treatment versus placebo (g = -0.64; 95% CI [-0.89, -0.39]; p < 0.001). There was not a significant reduction in pain outcomes for the oral treatment versus placebo (g = -0.26; 95% CI [-0.60, 0.17]; p = 0.272). CONCLUSION Topical medications were significantly better at reducing pain compared to oral medications versus a placebo in injured athletes. These results are different when compared to other studies that used experimentally induced pain versus musculoskeletal injuries. The results from our study suggest that athletes should use topical medications for pain reduction, as it is more effective, and there are less reported adverse effects compared to oral medication.

Litigation involving sports-related spinal injuries: a comprehensive review of reported legal claims in the United States in the past 70 years. Spine J 2023; 23:72-84. [PMID: 36028214 DOI: 10.1016/j.spinee.2022.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 08/05/2022] [Accepted: 08/17/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND CONTEXT Sports-related spinal injuries can be catastrophic in nature. Athletes competing in collision sports (eg, football) may be particularly prone to injury given the high-impact nature of these activities. Due to the oftentimes profound impact of sports-related spinal injuries on health and quality-of-life, they are also associated with a substantial risk of litigation. However, no study to date has assessed litigation risks associated with sports-related spinal injuries. A better understanding of the risk factors surrounding these legal claims may provide insights into injury prevention and other strategies to minimize litigation risks. In addition, it may allow the spine surgeon to better recognize the health, socioeconomic, and legal challenges faced by this patient population. PURPOSE To provide a comprehensive assessment of reported legal claims involving sports-related spinal injuries, including a comparative analysis of legal outcomes between collision and non-collision sports. To discuss strategies to prevent sports-related spinal injuries and minimize litigation risks. STUDY DESIGN/SETTING Retrospective review. PATIENT SAMPLE Athletes experiencing spinal injuries during sports. OUTCOME MEASURES Outcomes included verdict outcome (defendant vs. plaintiff), legal claims, injuries sustained, clinical symptoms, and award payouts. METHODS The legal research database Westlaw Edge (Thomson Reuters) was queried for legal claims brought in the United States from 1950 to 2021 involving sports-related spinal injuries. Verdict or settlement outcomes were collected as well as award payouts, time to case closure, case year, and case location. Demographic data, including type of sport (ie collision vs. non-collision sport) and level of play were obtained. Legal claims, spinal injuries sustained, and clinical symptoms were also extracted. Furthermore, the nature of injury, injured spinal region, and treatment pursued were collected. Descriptive statistics were reported for all cases and independent-samples t-tests and chi-square tests were used to compare differences between collision and non-collision sports. RESULTS Of the 840 cases identified on initial search, 78 met our criteria for in-depth analysis. This yielded 62% (n=48) defendant verdicts, 32% (n=25) plaintiff verdicts, and 6% (n=5) settlements, with a median inflation-adjusted award of $780,000 (range: $5,480-$21,585,000) for all cases. The most common legal claim was negligent supervision (n=38, 46%), followed by premises liability (n=23, 28%), and workers' compensation/no fault litigation (n=10, 12%). The most common injuries sustained were vertebral fractures (n=34, 44%) followed by disc herniation (n=14, 18%). Most cases resulted in catastrophic neurological injury (n=37, 49%), either paraplegia (n=6, 8%) or quadriplegia (n=31, 41%), followed by chronic/refractory pain (n=32, 43%). Non-collision sport cases had a higher percentage of premises liability claims (41% vs. 11%, p=.006) and alleged chronic/refractory pain (53% vs. 28%, p=.04). Conversely, collision sport cases had a higher proportion of workers' compensation/no fault litigation (23% vs. 4%, p=.03) and cases involving disc herniation (29% vs. 9%, respectively; p=.04). CONCLUSION Sports-related spinal injuries are associated with multiple and complex health, socioeconomic, and legal consequences, with median inflation-adjusted award payouts nearing $800,000 per case. In our cohort, the most commonly cited legal claims were negligent supervision and premises liability, emphasizing the need for prevention guidelines for safe sports practice, especially in non-professional settings. Cases involving athletes participating in non-collision sports were significantly associated with claims citing chronic/refractory pain, highlighting the importance of long-term care in severely injured athletes.

Abstract
BACKGROUND Health care utilization can vary by age group, geographic location, and socioeconomic status (SES). A paucity of information exists regarding the availability and utilization of medical care by injured scholastic athletes. The purpose of this study was to describe and compare injuries and health care service utilization by school SES over an academic year. METHODS Injury and health care service data was collected from 1 large school district. Percentage of free and reduced lunch (FRPL) for each school was calculated to stratify schools into high (<50% FRPL) and low (≥50.1% FRPL) SES groups. Incidence proportion and relative risk (RR) with 95% confidence intervals (95% CI) were calculated. RESULTS About 1756 injuries were reported among over 7000 participating athletes from 14 high schools. Similar injury incidence proportions were reported between high and low SES schools (RR = 1.10 [1.00-1.20]). Athletes from low SES schools were twice (RR = 2.01 [1.21-3.35]) and over three (RR = 3.42 [1.84-6.55]) times more likely to receive emergency and physical therapy care. SES was not associated with the use of physician, imaging, or surgery services. IMPLICATIONS FOR SCHOOL HEALTH, POLICY, AND EQUITY School medical providers and administrators should have ready and provide a list of trusted outside primary care and specialty providers that have experience in sports medicine. They should also enquire and follow up on which outside provider the high school athlete will seek care when referring out to outside providers. CONCLUSIONS Injury incidence was similar between high and low SES schools. However, athletes from low SES high schools were over 2-fold more likely to use emergency department services. Understanding factors influencing health care services choice and usage by student athletes from different socioeconomic backgrounds may assist sport medicine clinicians in identifying barriers and potential solutions in improving time to health restoration, athlete outcomes, and health care monetary burden.

Clinical Measures of Adolescent Softball Players With and Without Upper-Extremity Pain: A Preliminary Study. J Sport Rehabil 2022; 31:971-977. [PMID: 35523422 DOI: 10.1123/jsr.2021-0096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 03/20/2022] [Accepted: 03/22/2022] [Indexed: 11/18/2022]
Abstract
CONTEXT Upper-extremity (UE) pain is a concern among softball adolescent athletes. However, research on preseason screening of demographic characteristics and clinical measures among those with and without UE pain among adolescent softball athletes is underreported. This study sought to present functional outcomes and clinical measures of shoulder and hip complex flexibility, range of motion (ROM), and strength in adolescent softball athletes with and without UE pain. DESIGN Cross-sectional study. METHODS Sixty-seven athletes were assessed at the start of the spring season. The Kerlan-Jobe Orthopedic Clinic Shoulder and Elbow Questionnaire was administered to determine UE function. UE measurements included shoulder ROM, flexibility, and strength; lower-extremity measurements included hip ROM and strength. These variables were reported for players with and without UE pain as mean and SD. Independent samples t tests were performed to analyze differences between the groups. RESULTS Thirteen (19.4%) athletes reported UE pain during preseason screening. Mean Kerlan-Jobe Orthopedic Clinic Shoulder and Elbow Questionnaire score among athletes with UE pain was 58.0 (17.6) compared with 97.1 (6.9) for athletes reporting no UE pain (P < .001). Athletes with UE pain presented with significantly less dominant side external rotation ROM (UE pain: 106.5 [10.4], no UE pain: 114.6 [11.3]) and total ROM (UE pain: 163.7 [14.5], no UE Pain: 174.8 [14.3]). CONCLUSION These findings inform clinicians on function and preseason clinical measures in adolescent softball athletes who present with or without UE pain. Athletes with UE pain demonstrated lower outcome scores indicating likely impact on overall UE function. These athletes also appeared to demonstrate UE ROM differences compared with athletes without UE pain. Further research is needed to investigate larger sample sizes and positional differences at baseline and throughout the season to determine if clinical measures used in the current study are risk factors for pain and injury.

Tarkhan AH, Anwardeen NR, Sellami M, Donati F, Botrè F, de la Torre X, Elrayess MA. Comparing metabolic profiles between female endurance athletes and non-athletes reveals differences in androgen and corticosteroid levels. J Steroid Biochem Mol Biol 2022; 219:106081. [PMID: 35182726 DOI: 10.1016/j.jsbmb.2022.106081] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 02/09/2022] [Indexed: 11/24/2022]
Abstract
Endurance training is associated with physiological changes in elite athletes, but little is known about female-specific effects of endurance training. Despite the significant rise in female sports participation, findings from studies performed on male athletes are largely extrapolated to females without taking into consideration sex-specific differences in metabolism. Subsequently, this study aimed to investigate the steroid hormone profiles of elite female endurance athletes in comparison with their non-athletic counterparts. Untargeted metabolomics-based mass spectroscopy combined with ultra-high-performance liquid chromatography was performed on serum samples from 51 elite female endurance athletes and 197 non-athletic females. The results showed that, compared to non-athletic females, certain androgen, pregnenolone, and progestin steroid hormones were reduced in elite female endurance athletes, while corticosteroids were elevated. The most significantly altered steroid hormones were 5alpha-androstan-3alpha,17alpha-diol monosulfate (FDR = 1.90 × 10-05), androstenediol (3alpha, 17alpha) monosulfate (FDR = 2.93 × 10-04), and cortisol (FDR = 2.93 × 10-04). Conclusively, the present study suggests that elite female endurance athletes have a unique steroid hormone profile with implications on their general health and performance.

Abstract
Collegiate athletes have demonstrated a need for social support to help cope with their daily responsibilities. The purpose of this research was to explore National Collegiate Athletic Association Division II athletes’ perception of social support from friends, teammates, family, coaches, significant others, and athletic trainers following injury, illness, or other identified life stressors. There were 546 participants who completed a five-part survey using the University Stress Scale, the Multidimensional Scale of Perceived Social Support, the Athletic Multidimensional Scale of Perceived Social Support, the Perceived Stress Scale, and a demographic section. Of the participants, 352 (64.5%) stated that they experienced moderate stress levels, and all participants indicated experiencing an identified life stressor within the last 12 months. The results indicated statistically significant differences when comparing providers of social support: females preferred the support of friends, significant others, and athletic trainers, and freshmen and sophomores perceived more social support from friends than did juniors and seniors.

Effect of Quercetin on Injury to Indomethacin-Treated Human Embryonic Kidney 293 Cells. Life (Basel) 2021; 11:life11111134. [PMID: 34833010 PMCID: PMC8623736 DOI: 10.3390/life11111134] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 10/18/2021] [Accepted: 10/19/2021] [Indexed: 12/03/2022] Open
Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat inflammation and pain and even to prevent the progression of cardiovascular disease. They have become widely used because of their effectiveness, especially among athletes performing high-intensity training. Indomethacin is used for pain management in sports medicine and is highly effective and versatile. However, several clinical studies have reported that indomethacin induces acute renal damage. In the present study, we determined that indomethacin reduced human embryonic kidney 293 (HEK293) cell viability in a concentration-dependent manner by triggering apoptosis. In addition, we demonstrated the effect of quercetin on indomethacin-treated HEK293 cells by inactivating the caspase-3 and caspase-9 signals. Furthermore, quercetin reduced ROS production and increased mitochondrial membrane potential (ΔΨm) in indomethacin-treated HEK293 cells. Our results indicate that quercetin can interrupt the activated caspase and mitochondrial pathway induced by indomethacin in HEK293 cells and affect apoptotic mRNA expression. Quercetin can protect against indomethacin-induced HEK293 cell apoptosis by regulating abnormal ΔΨm and apoptotic mRNA expression.
