    Abstract Insects such as the black soldier fly (BSF) are recently being studied as food sources to address concerns about how to meet the food demand of the growing world population, as conventional production lines for meat proteins are currently unsustainable sources. Studies have been conducted evaluating the use of insect proteins to produce extruded foods such as expanded snacks and meat analogues. However, this field of study is still quite new and not much has been studied beyond digestibility and growth performance. The purpose of this work was to evaluate the compatibility of protein extracted from BSF flour with corn flour starch within an extruded balanced shrimp feed model through molecular dynamics simulations, for which cohesive energy density and solubility parameter (δ) of both components were determined. The calculations' results for the protein molecule systems yielded an average δ of 14.961 MPa

    Abstract The removal of total petroleum hydrocarbons (TPHs) from contaminated mining soil was carried out under in vitro conditions. The aerobic consumption of TPH in the slow bioremediation stage via biostimulation with native microorganisms and biostimulation-bioaugmentation with autochthonous fungal isolates was evaluated. The initial TPH concentration was 70,880 ± 975 mg TPH/kg soil, soil was amended with nutrients at a C:N:P ratio of 100:15:1, the water content was adjusted to the soil field capacity, and batch microcosm reactors were incubated at room temperature (20.5 ± 3.1°C) for 90 days. The bioaugmentation process was tested using four hydrocarbonoclastic fungal strains isolated from the same contaminated mining soil individually and a mixed culture of the four isolates. The molecular characterization of the isolated fungi was based on sequence analysis of 18S rRNA, and the fungi were identified as Aspergillus niger MT786339.1, Aspergillus fumigatus MT786338.1, Aspergillus terreus MT786341.1, and Aspergillus flavus MT786340.1. The best TPH removal was achieved by inoculation with the fungal consortium (57 ± 1.97%) at 45 days (slow stage) after initiating the biostimulation process, followed by inoculation with Aspergillus niger (49 ± 1.2%), Aspergillus terreus (44 ± 0.67%), Aspergillus fumigatus (35 ± 0.98%), and Aspergillus flavus (32 ± 0.38%), while the degradation rate achieved with native microorganisms was only 21.6 ± 1.5%; statistical analysis of the results showed significant differences.

    Abstract Background: Literature about long implants used together with a minimally invasive spine surgery (MISS) technique is scarce. Our objective is to contribute our surgical experience in this field and to specifically focus on several technical details.
    Patients and methods: A digitally-dissected canal along the paravertebral muscles was created linking the stab wounds on each side in relation with the pedicles to be cannulated. Screws were inserted following the percutaneous technique. Long rods were modelled, threaded through the extender sleeves along the paravertebral canal and pushed into the screw heads with the reduction forceps. When fusion was needed, the facet complex was decorticated with a drill. To insert a cross-link, a canal between the 2 rods was digitally created and the spinous process was drilled.
    Results: 8 patients underwent surgery (age range: 25-77 years). Indications were postosteomyelitis kyphosis in 3 patients, bone tumor in 3, and spine fracture in 2. No blood transfusions were necessary during or after surgery. A cross-link was inserted in 2 patients. Posterolateral bone fusion was attempted in 4, but radiologically identifiable in none. In one patient a cantilever manoeuvre was done to correct kyphosis. Mean duration of surgery was 4 h. There were no clinical complications related to the operation or the hardware (mean follow-up of 7.14 months, range: 1-15 months).
    Conclusion: The application of MISS techniques can be broadened to long spinal constructs to assess fractures, tumors or deformity, especially in elderly or debilitated patients. Nevertheless, posterolateral fusion is still a challenge through these limited exposures.

    Abstract Lignocellulosic wastes may provide a means to economize polyhydroxybutyrate (PHB) production. This study has proposed the use of Agave durangensis leaves obtained from the artisanal mezcal industry as a novel substrate for this aim. Results revealed an increase in PHB biosynthesis (0.32 g/L) and improvement in %PHB (16.79-19.51%) by Bacillus cereus 4N when A. durangensis leaves used as carbon source were physically pre-treated by ultrasound for 30 min (ADL + US30') and thermally pre-treated (ADL + Q). Chemical analyses and SEM studies revealed compositional and morphological changes when A. durangensis leaves were physically pre-treated. Also, elemental analysis of growth media showed that carbon/nitrogen ratios of 14-21, and low nitrogen, hydrogen, and protein content were well-suited for PHB biosynthesis. Confocal microscopy revealed morphological changes in the bacterial cell and carbonosome structure under the influence of different substrates. Finally, Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) analyses showed that homopolymeric PHB with a high thermal-resistance (271.94-272.89 °C) was produced. Therefore, the present study demonstrates the potential use of physically pre-treated A. durangensis leaves to produce PHB. These results promote the development of a circular economy in Mexico, where lignocellulosic wastes can be employed to produce value-added biotechnological products.

    Abstract Background context: Aneurysmal bone cysts at the cervical spine represent a real challenge both diagnostically and therapeutically, especially in young patients.
    Purpose: We present an unusual case of a C2 aneurysmal bone cyst expanding in the entire vertebral body in a girl successfully treated with a transoral vertebroplasty.
    Study design: This is a case report study.
    Methods: We report the case of a 17-year-old girl with a history of cervical pain and occipital headache after a car accident. Routine x-rays disclosed a C2 lesion. Her neurologic examination was normal. Computed tomography showed a lytic lesion occupying almost the entire body of the C2 vertebra. The cortical bone was intact but notably thinned. Magnetic resonance imaging revealed a cystic image with blood inside. Transoral vertebroplasty was selected among other surgical options for the following reasons: (1) to improve the clinical symptoms, and (2) to prevent future vertebral collapse with devastating neurologic consequences. Under general anesthesia and continuous neurophysiological monitoring, we conducted a fluoroscopic-guided transoral vertebroplasty through a Jamshidi needle. A cytology sample from the cystic lesion was taken through the needle.
    Results: The blood smear showed no tumoral cellularity. There were no complications during surgery or postoperative infections. After 4 years of follow-up, the patient is pain-free and leads a normal life.
    Conclusions: Transoral vertebroplasty seems to be a direct, safe, and effective technique to stabilize cystic lesions that endanger the stability of C2 and to improve symptoms. Aneurysmal bone cysts should be included in the differential diagnosis of lytic lesions at the C2 vertebral body.

    Abstract Objective: To describe a rare complication of the extreme lateral interbody fusion technique.
    Background: Lateral lumbar interbody fusion (LLIF) is a minimally invasive technique that has achieved great reputation among spine surgeons because of its advantages over other procedures. However, complication rates of this technique have not been definitively assessed so far.
    Case report: A 44-year-old male smoker, presenting with pseudoarthrosis of a previous posterior stabilization, underwent an LLIF procedure. The operation was uneventful, and an appropriate functional recovery was achieved by 2 months after surgery. Nevertheless, 5 months after surgery, the patient developed pulmonary tuberculosis and a mass in the proximity of the LLIF incision appeared. This mass was finally diagnosed as abdominal pseudohernia and had to be surgically repaired.
    Conclusions: Abdominal pseudohernia is a rare complication of LLIF procedures. The interest of the present case is 3-fold: 1) it is the first delayed case of abdominal pseudohernia after an LLIF procedure; 2) it is the first case described in a young patient in whom risk factors have been identified and discussed; and 3) it is the first case that did not resolve spontaneously and required surgical repair. This exceptional complication must be borne in the mind of the spine surgeon when using the LLIF technique, and special precautions, such as laxatives or respiratory physiotherapy, apart from meticulous atraumatic dissection and closure of the abdominal wall and specific intraoperative monitoring, should be taken in high-risk patients to prevent it.

    Abstract Background: Literature about long constructs in the cervicothoracic junction (CTJ) implanted with a minimally invasive surgical technique is practically nonexistent. Our objective is to present a less invasive-minimally invasive (LIS-MIS) surgical technique to stabilize the CTJ.
    Patients and methods: A midline cervical short incision was made, three or four level lateral mass screws were inserted bilaterally and rods were placed in a conventional technique (LIS field). Percutaneous screws were placed in the upper thoracic spine, and thoracic rods were threaded subfascially through the pedicle sleeves up to the cervical incision (MIS field). Cervical and thoracic rods were linked with parallel connectors. Two cross-links were used in each case.
    Results: Two patients (33 and 53 years of age) with instability of the CTJ due to metastases were operated on in this way without attempting bone fusion. Mean duration of surgery was 7.5 hours. No patient required blood transfusion. There were no complications related to surgery or the hardware. Opioid consumption diminished after surgery, and both patients remained ambulatory until decease.
    Conclusion: This LIS-MIS technique seems feasible to stabilize the CTJ in very selected cases when fusion is not necessary.
